After several weeks of owning the
FLEX XC3401 VRG Orbital Polisher I can say it's the best polisher I have used. I have tried the PC,
UDM, and Hitachi Rotary. It is butter smooth and you can tell the stroke length is 8 mm. Just like a hand application. The microprocessor offers constant speed control by tachometer generator, soft start, accelerator trigger switch, restart protection after power interruption, overload protection, temperature monitoring, and speed selection. It's a dream to use!!!
