To test the invoice please excellent really well done

Excellent extruder, recommend!

Can be compared with Prusa MK3 gears.

Easy assembly works at the top on a Ender 3

good quality

Wow, its a nice extruder, it has a good strenght to pull and push the filament, the materials feels hard and strong, very recommended, and the shipping was too fast.

The extruder was sent immediatly and arrived very fast, however the quality of the product is less than optimal, the gears are not ideal and move against each other with noticable resistance.

this is an awesome bit of kit. excellent build quality and works like a dream.

Well packed, fast shipping, looks great build quality, recommend this seller, thanks, 5 *****


All super good and fast, it's already installed and if it changes enough (ender 3)

overall good quality but the spring that keeps the filament tight is too strong, so it leaves marks at the filament. Can be fixed pretty easily though.

Well made everything works exactly how it should.

What an awful company to deal with. I ordered 3 of these and they sent two together and one separately. not sure why??? I didnt receive the 3rd extruder. I contacted the company to let them know and they told me that it's been signed for. I didnt have to sign for the first 2! the lack of replies from the company shows they dont care. I made a claim and lost $45 due to nobody caring about the customer. an automated reply stating I had to supply a lost parcel form from my carrier. I called my post office and they stated there are no forms like that and said to me that its theory way to get out of having to refund me the money. shady!! if you purchase something with value, be prepared to lose your money because claims dont help at all. I have a very good rating on aliexpress and purchased lots of stuff from triangle labs but I will never buy from them again and I will make sure everyone on social media hears the truth about this company. They are completely unprofessional in my opinion.

Good sound

All good and work perfectly...

Works fine

thank u

Items are as described. Good packaging, quick shipping.

If you can't buy the original, this is the best. 100% recommended. Machined gears.

working well on my ender 3. thanks!

Super Free! Top Quality! Very satisfied!

it was perfect for my needs

Accurate and fast shipping

Seems fine so far, good quality, fast shipping to colombia

The feeder is excellent, does not spoil the rod-i think to take another one for the second extruder. While put in the opposite direction, so as not to climb into the firmware, but, probably, i will leave-the design of the rollers is symmetrical, for bowden the direction does not matter. I recommend to buy.

works like a charm

Very good extruder. I recommand strongly !!!


Best BMG clone I have ever had!

Works great. Included bracket does not fit Ender 3, and mounting it on top is a bit to close to the z-rod imo. Print a bracket from thingiverse and you'll be fine :)


All seems to be as described, not tested the product

Perfect arrived as described and thus far is a great product

Very fast Delivery. All as described.

Perfect clone

fantastic. love this thing

Wery good knock-off product, have used this in a Bowden setup, works like a dream.

Excellent. Much better quality than Bigtreetech!



Fast shipping

AWESOME Extruder , the drive Gears are well made and the Filament grip is stunning.

Excellent quality

Alles super

Product are in very nice quality, too bad you have to pay so much extra for shipping, its all combined in 1 package, but have to pay for all shipping seperate..

All right, pending testing.


Looks very nice, packaged in handy smal box.

very good and strong Extruder.

Everything fine.


Perfect feeder. In other reviews everything is already described. Thank you store.

Fast quality Trianglelab us dwelled. Recommend to me is the best sellers of AliExpress.

haven't tested it but feels like a quality item

After trying the first BMG extruder, I was so satisfied that I ordered another 3. The quality is excellent and there's no filament that he can't push.

Just perfect clean and smooth. Thank you! I recommend this seller!

Everything is fine! Works just fine!

It came quickly, packed in a cardboard box (the box was crushed by our good mail) but when opened the box inside there was a plastic box and there was a extruder in it. Everything is whole, and neatly decomposed by bags, but i did not find grease in the box, maybe it should not be of course, but on the video on youtube saw that the grease was. It doesn't matter. And so everything is super. I advise the goods and the seller.

Shipped fast, thank you!

Fast delivery, packing and package chic. The extruder has nothing lyuftit, it's nice to hold. After installation and verification, i will add a review.

The screws is a little bit short for my case of usage, everything else is good.

Very high quality performance

As described. Work well

Good quality

All right great seller

Fast service, quality product.. thank you

SUPER! I am positively surprised appearance and quality. Ekstruder threads perfectly and his work is perfect... I am shocked! Recommend. Pack dotarła in under 14 days.

Well packed and positive first inspection, testing the printer

Product conforms to my expectations, pack well and works perfectly well.

All good. Thank you

Super fast delivery! Many thanks.

Very good.

TOP productsTOP productsTOP products

Had to drill a hole bigger for filament passthrough as two holes on top and bottom of drive wheels do not line up. Hopefully more flexible filaments would not have problem with that

Excellent quality. Definitely recommend.

Larger size

I bought it myself and a friend and put in and pull out the filament for bowdem is horrible. He also loses steps. I'm not going to claim it to the seller because it's hard to prove. Pero 30 € pulled to the litter

Fast delivery and well packed! Not tested but looks good!

perfect unit, never tear or damage filament, almost 9kg pressure before pushback, silent and ultrahigh speed for retractions.

Excellent quality, more expensive than the rest, but it's worth it. Thank you seller!

I was very impressed, the quality seems higher than usual.

Thank you!


It was delivered with the wrong bracket/adaptor to fit the Creality Ender 3.

Seller excellent, goods qualitative

Thanks veri fest delivery



1 to 1 clone.

Quality at a high level! I recommend!

Mounted on ender 3, Assembly without modification nothing wrong

I am very satisfied with the product.

Super Product I would it each zwit again buy!!!

Fast delivery - product as described. Thank you.

gotta love dual drive

Without riding it, it looks very good.

Well received! Second opinion after editing if problem


The details are qualitative, doubt only causes plastic gear.


Recommended. Use this but 짭 짭 BMG favorable price and nicer. Is still 짭 짭 four kinds of high school has four... Attachment for A grade 짭, you owe it to yourself. Not Bond texture genuine.

Everything perfect

looks good, have not tried it yet

Great design, and dead easy to install. In just 5 minutes it was installed in my CR-10S.

Good quality. Accurate description. Quick dispatch.

Thanks you very much, good seller

Everything is wonderful! True, a little long went the goods)))

All right and right, all in order, pretty quick and good article at first glance, we'll see how he behaves with use.

All good so far. Just works.

Delivery ahead of schedule. Very well-wrapped, protected with bubble plastic and sponge inside the box. The article is of quality, good feeling to touch. Article as described. I'm waiting for the hotend of this brand to install it. Recommended.

product ok

Thank you all good!

Incredible value. very high quality. might even be better than the original bondtech. Shipped to canada in less than 2 weeks

Works Perfect

Excellent extruder, recommend! Compared to default direct drive-sky and earth. Now no surges and spills at high speeds. And the noise seemed to be less during the retroattacks.

Excellent tolerances. Very impressed.

Excellent !


Everything is fine, delivery 7 days

Product looks good and well made. Will know when I test it.

The quality of the product is very good. At the moment it works properly. The product arrived fast. I recommend both the product and the seller.

love this extruder. ordering a bunch more for the rest of my printers after using this one.

Faster than expected shipping, quality is decent for a clone.

Fast delivery and product according to the description

As described, no problems

Really good quality product!

Very good as always!

Wow. This is the best quality. I purchased same type from another seller as it was cheaper, I wished I didn't and should have spent the extra money to buy it from TriangleLabs. This is far superior in quality. You will not regret paying the extra money. As I have purchased 2 of these extruders, I can tell you that this one from TriangleLabs is far better. For example, loading filament is alot easier and smoother. The cheaper one is harder and takes longer to load because the hole is too small. The screw that holds the lever fits perfectly with the right amount of tension. On the another extruder, it's alot harder to screw the lever down, the spring is too tight or the screw supplied is not the right size. My advice, spend the extra few dollars because you will save money in the end. It's a better product and that's why it cost more. I have learnt my lesson.

Extruder is working very well.

As described

order arrived on time,unable to confirm order received until i returned from vacation

Haven't tested it yet, but the quality looks impressive. Very fast shiping and really well packed!

Perfect and all very well presented

Received without problems all right need to prove it

Really satisfied, I have an original Bondtech on another machine but this ones working just as good.

Seems okay, not sure if it's worth the extra money compared to other clones. (Time will tell.)

Arrived on time, the quality is excellent

Very fast delivery. Everything as descripted.

Box was damaged due to poor packaging.

All bestens.

well packaged not installed yet but looks good

Super fast delivery. Less that 1 week to Europe. Very well packed for delivery!

Quality is really high. Very good extruder.

Good product, well packed, not yet fully test but satisfied

Extruder of excellent quality, delivery fast. Thanks to the seller.

looks great so far looks like perfect clone the hole lines up with gears cant wait to get it installed

I never get there

Super Quality, and very quickly.

Crush fire and does not bustle

I am not disappointed with the quality of this product.

As usual, the quality is great. Until i checked

Quality at first glance is excellent. How to install so i will add feedback

Great product! Almost as good as the swedish original.

2 weeks rewelacja

Super Effective more slamming problem with this extruder, good quality

It works very well.

Great seller, higher quality at lower prices and shipped fast.

It goes well, but to place it on the ender 3 you have to print an adapter, the one that comes out doesn't go to him, and put it right up with the z spindle.

Grab the filament and push it hard, no more jumps.

great extruder my retraction with petg went from 4.25mm to 2.75 with almost zero stringing. No more pressure issues with the extruder clicking and not being able to keep up. Just remember you need to download a gcode to load and unload filament.

Bolts are short, if the wall is more than 2mm it is necessary to look, and the hat does not fit any

Perfect extruder! Except for the fact you have to sand it down to make it fit an Ender 3 or CR-10. Otherwise it'll grind on the Z-rod.


Good shopping

Exelent product, fast shipping.

Expensive but works like a clock. The kit includes very short screws (35mm) for attaching the extruder to the engine.

Great thank you very much:)

like it!

the plastic could be better than the current one, but for this price i'll be happy about it

Good product fast shipping good shop

Good Quality. Fast Shipping

The set screws are very shallow and an allen key cannot turn without worrying about stripping. Gear was installed in wrong location and did not line up the hole. Once adjusted it works well but the set screw was an unplanned frustration. Also, bracket is not suitable for CR10s so buyer beware you will need to print a new one before installation.

Nice item fast shipping

Fast shipping and item works great. Has improved the quality of my prints. Thanks.

Mycket bra.

everything ok

I 've tried it a week with long prints, no problem perfect flow is a past. Mounted on an anet a8 retraction 3.5mm extruder 415 steps. Over 60 hours running without fail. The only drawback is changing filament

All ok. I did not check in the work.

Order received in kind all ok!

Perfect thank you;)

good precision

Installed on an ender 3. at first it costs to prime the filament a little but then no problem. Calibrating is teps is fundamental, starting around 400. It's pretty good quality and i have no problem at the moment.

Good quality replica, works as well as the original.

Very good presence, very fast to arrive and also works to a thousand wonders

all seem to be ok and good quality.... the only thing that I can complain is that do not arrive any kind of instructions for the asembly or installation.....I thing that they can at least send a url address to videos or instructions ..... anyway that is the only cons....that I see until now..... I do not installed yet....

Very good quality in materials, assembly and finish. I recommend it

Arrived in 15 days thank you very much

Delivery after Germany only 12 Days. i am amazed. The Product makes a very good Impression.

This one looks great. Feels like a quality product. I’m looking forward to test it. All metal parts are top notch. Fast shipping.

not tested yet, quality looks pretty good, delivered in a nice box which can be re-used to store small things

I just installed it on my creality cr-10s. Only problem is that the bracket that follows the product does not fit the cr-10s, so you either buy one that fits or print one. But other than that, the extruder performs flawless. It really shows improvements on printed parts. If you are looking for a new extruder, i can recommend this product. 10/10

Lovely extruder. Already put and tried, i will take for the second printer.


i accidentally press finish button. I have not received it yet.

As usual - Triangle Lab's clones is "The best!". A+++++

Great clone original bondtech at 1/3 of its price

I 've been in many hours of use and great, very good quality in materials. In the ender3 you don't need the attachment or limarlo how i read out there fits s perfection, i'll buy it again for another machine, it's very strong.

Great quality! Metal gears included with the coupler spacers! With handy box!

as described. surprisingly quick delivery to uk

Gears that pull the filament were ok as advertised. The gear that goes on E motor shaft was of low quality, poorly machined, lacked precision.

Best clone I've found. Gears are very well made.

Well done. Came quickly. Quality at altitude. Worth your money. In the work has not participated, the printer in the assembly process. With the seller did not communicate

The extruder seems very good quality when i mount it and try it i will comment for now everything perfect

Ok, good seller, fast shipping

I haven't tried it. it looks good.

Everything is super.

It took 17 days

After installing it and testing it on a couple of long prints, i must say i'm 100% satisfied. It's excellent.

Very good extruder. Fast shipping. With this extruder skipping is impossible. It is better than Titan but not necessarily worth upgrading. If you have the most basic extruder like I had then it is definitely worth it. I can recommend it.

Everything is good except communication with the seller. No question answered as much as i did not ask him.

I arrive well protected and in exelent conditions.

Delivery time 23 days, thanks to the seller! A good feeder, it's not just praised. Good value for money.

Sending fast, reached 16 days to the moscow region. Packed qualitatively, everything corresponds to the claimed. Seller recommend.

Fifteen days late in the order but product in accordance with the description

As always the. best shop products of very good quality

Installed on Ender 3 with offset and a spacer for one hole. Extruder works great, grips filament superbly and have had no skipping or issues, it is more difficult to load filament as the teeth grip really well, and I have to now use GCode to load the full PTFE tube of filament when changing out.

À tester

Extruder with great quality and finish. Considerable improvement in consistency of printing, silent.

Super on alfawise u20

Everything perfect and very fast, as always

Flawless as usual, best gears on Aliexpress.

--Perfect quality and sizes, lovely quick service thank you

perfectly fits anycubic mega i3. it improves a lot printing quality. for loading and unloading filament I use simple scrips, just google for more info.

I like it. good to work.

Good quality, no jambs. Did not lubricate anything, immediately into work)

Excellent, perfect packaging, fast shipping, received in a little less than 2 weeks, very good products, beautiful finishes, very happy with my purchase, I recommend.

Looks good, have him still mount

Very accurated and functional.

Excellent as always! Thank you!

All OK

Delivery three weeks. Appearance quality is good. I will collect, i will add.

good product and fast Seller

Thanks for the timely delivery.

The extruder gently and smoothly now pulls, does not dampen the plastic, hotend gently and smoothly melts, the temperature sensor exactly shows the temperature. The quality and speed of delivery is very satisfied. I will order more! Thank you!

Fantastic product

Everything works fine, the quality is super! Thank you!

Didn't get the chance to test it, but seems a bit wider at the base than the original Bondech BMG. Nevertheless great item. A++ seller.

Good thing. Made qualitatively, nice to take in hands. Presses well.

Goods conform to the description. Very good quality. Very fast delivery. I recommend this Seller.

I send something slow, but within the deadline it adjusts the description

Great! Corresponds to the description!

Excellent quality but in aluminum fitting brass washer was pressed by the wrong side, the seller sent a replacement

Excellent product is functional with high quality. Great vendor.

Quality unexpectedly high, the best you can buy in china

Quality is quite good and it works on my machine.

Everything is fine, well packed, delivery in normal time

Quality is decent. Delivered quickly. Packing is super.

Quality standard

Good product, works great except it's almost impossible to push/pull the filament manually when pushing the arm, I need to remove the screw and get it open otherwise the gears will still hold the filament.

Thank you for the very good product !

I can't print flexible strands, get stuck in the gears and don't extrude, does anyone know how?

Great product, packaging and fast shipping!

Fast shipping. Thanks


Works great !

really pleased with the quality of this

The product is accurate to the description. I haven't tried it yet when i try it well i add comment

Very good product. highly recommended seller. fantastic attention

Excellent quality, requires separate calibration

Great stuff. Can’t wait to install it on my CR10S4

All apparently well, not to prove it

Godsendt Upgrade for my ender 3!

As always, "triangles" at a high level.

I received a very well designed and developed extruder yet I haven´t installed it yet. The product description is accurate and well written. All the infos I needed are there.

Great extruder, easy to assemble and install.

Amating quality.
