Good quality. Some of the rollers are a little deformed and there is a bit too much play on the roller shafts. Some suggestions to improve this wheel for customers and manufacturer: (1) Consider to place the shaft flange INSIDE the wheel cage. It reduces the minimum distance between the wheel and motor from 14mm to 9.8mm. More compact designs are then possible and lesser strain on the motor bearing and the moment arm is shorter. It saves you money because the brass spacers need each be 4mm shorter. Stronger and lighter weight is the result. With this modification it is even possible to place the hub completely inside the wheel cage. TAKE CARE to leave the shortened the brass studs with a perfectly flat face otherwise your wheel won't be true. (2) To fix the roller play on their shafts... Disassemble the wheel and take out the rollers. The little plastic cap can be pulled off easily. Add a small m3 washer on one or both ends but ensure the roller still runs free. Probably good wheel maintenance as well as lint will build up over time. (3) Consider to have the grub screws that fasten on the motor shaft rotated by 22.5 degrees so the bolt heads won't interfere with the grub screws.
