Well after much reading and reviews I bought my first rotary ( Metabo ). When I first used the machine it seemed like a solid unit. I used it for a few hours without any problems with a 6 inch edge durofoam pads. When I changed to a bigger edge 8 inch pad the unit started to get hot and started to make cluncking noises :nervous: ... as some time passed the unit started to glitch and it seemed to get stuck even thou the motor winding was still turning inside of the machine. I let the machine cool down and with my detail left incomplete I proceeded to try again. The machined started to miss more and more untill it would not rotate any more with any kind of load on the machine. Called toolfetch.com and have still not recieved a call back... anybody else have the same experience as me??? I'll keep you posted as to what went wrong and until then I've ordered a makita polisher :nervous2:
