Perfectly packed, works fine, very silent, (no vibrations), no heating (I tested the kit for 8 hours at 24000RPM) the motor with load at 3,8 Amps (I used another motor that I always use for measuring torque through a constant load, and currents of motors, coupled "axis to axis" to obtain "lab accurate" parameters (yes, I am an engineer and I design industrial grade machine tools for a living)
The product received. The price, the quality is excellent.Thank you very much.
