## Customer Reviews

### ⭐⭐⭐⭐⭐ Bondtech is quality...
*by C***S on August 21, 2020*

My extruder was worn out. I tried replacing it with one of those cheap aluminum extruders. What a disappointment. This was the worse design I have seen. Then I tried a cheap "knock-off" of the Bondtech extruder. While it worked most of the time, it still had it's problems. One of the worse was that once the filament was in, it was next to impossible to get it out.Then, I bought the expensive Bondtech extruder out of frustration. It was easy to install and best of all, it WORKED!! It was easy to load and easy to unload. Yeah, it cost more, around $100, but after using it for a few prints, I am not taking it off. It works, I don't have to worry about it. My prints come out great and it works!Buy this one, you will be glad you did once you use it.

### ⭐⭐⭐⭐⭐ Just works
*by B***T on July 13, 2021*

I can't speak to any of the reports about fake products, but mine was genuine. And it works flawlessly on my Ender 5. I have purchased an off-brand knockoff and was not satisfied at all with the quality on it. The price is high, but you do get what you pay for. I've tried 4-5 different extruders and this is by far my favorite. Goodbye under extrusion, goodbye extruder blowouts.The only thing I could possibly ding this for is that manually removing the filament for a mid-print filament change is a bit of pain, but it manageable and a small price to pay for the reliability that I get from it.

### ⭐ Not like the quality I've seen before from bondtech.
*by N***K on August 26, 2018*

I'm seriously questioning if this is authentic. This is my second bondtech bmg extruder but this one is questionable. The gears would not turn when I was inspecting alignment. I found the housing had a lot of plastic shavings and some metal shavings. The stepper drive gear has rust spots (speckled) and some surface rust. After brushing out the debris and wiping off some grease filled with debris it still doesn't turn freely like my other bmg extruder -slight grinding. Also the filament path is jagged on the top portion and I can see white I believe the black is a coating and white underneath. Anyway seriously disappointed it doesn't match the quality of my first bmg extruder and honestly makes me feel like it is a clone or was missed in quality control.
