Looks to be good quality. Make sure you have a hex driver small enough for the set screws.

Very poor quality. It is unusable, because holes have 4.15-4.20mm, while shafts of my motors have precisely 4.00mm, so it causes 2-3mm deviation on the top end of adapter and large vibrations.

Bought at handfull of these just to throw them away. The hole is too off center / skewed and it results in massive vibrations.
