Excellent if you want to increase print speed
I bought this together with some powerful fans so I can increase my print speed. It took me a while to get this calibrated correctly but it was worth the effort! Before, I printed at 80mm at the fastest with around 50-60mm being my average to get quality prints. Now, I print at 150mm with 4000 acceleration and still get nice prints! I'm sure with more calibration, I can get this a bit faster. But for now, I'm happy cutting my print times without sacrificing quality!

3.0 out of 5 stars Working as intended? UPDATE 10/17
Reviewed in the United States on September 30, 2022
The replacement I received seems to be doing its job but, it certainly doesn't inspire confidence. After the replacement came I installed it in place of the defective extruder and was surprised at how much quieter it was compared to the first. However, in about an hour the new one started making as much noise as the first. The new replacement is not having the same print quality issue that the first one did but, I feel like its only a matter of time before this one fails based purely on the amount of concerning sounds coming from it.

Bearing seals on both sides of the main axel bearings sheared off after 12h of use. The extruder was noisy out of the box and I have had issues with slipping during retract unretract moves causing issues with print quality. Seems like it has potential but the inconsistent feed issues make good prints impossible. I'm currently waiting for a replacement and will update once installed.
