I have recently purchased this spindle motor with chuck and collet. It spins very fast, 14200 RPM at 19 Volts. It is loud, but that is expected with an open fan. It is well balanced for both weight and chuck centering, hardly any vibration. The noise suppression PCB is just an add on with SMD capacitors to short out noise. The PCB is not sufficient, I use an additional L-C filter to prevent noise entering the CNC circuits. The PCB has a convenience LED to indicate power on for the motor. The chuck looks and feels like hardened steel and has smooth machining. No visible wobble on outside or inside when spun slowly. My 0.5mm 1/8 inch end mill stays centered when spun and observed through a magnifying glass. The motor brushes are large, should give a long life time. My seller shipped fast. I think it is worth the investment, much better than my stock spindle motor that came with my mini CNC.
