To my surprise, about 50 hours of use my Gen 2 broke off while I was in Speed setting #6, projected to my metal garage door and dented in about 1 cm deep
It was a very close call and the part where you mount the backing plate separated from the rest of the polisher during high speed
It looks like it was "punched in" from factory and the defect looks like it spun against the body, shearing some metal bits and pieces.
I will post some pictures but I just want to warn everyone that if your DA is "vibrating" or noisier than the usual to inspect and stop using it
I'll be sending it back for repair but worried about Canadian shipping rates and other duty or taxes
I also just bought the Gen 3 to finish the work and it was a night and day difference
My take on it is that prolong usage of the DA in one session causes the heat transfer from the motor to the mechanism causing the metal to gradually expand over time, the slowly separating itself from the rest (I am talking about the nut and rod where you screw in the backing plates)
Thanks for reading and I'll post pictures when I get back from my trip
Cheers
