Review on 💪 Efficient HYCHIKA Grinder: High-Speed 10000RPM Grinding and Cutting Power by William Stewart

Convenient key position. very convenient. difficult to assemble in tight spaces. enough time to use the battery. but they tend to weaken after repeated discharge and recharge. or should i say the power goes out earlier. I want it to stand on edge when the battery is installed won't balance. You have to put it to the side.
