Review on K1140 Drilled Slotted Evolution Ceramic by Randy Brimmer

Actually the first great product although I got my money back. after about 8 months the left rotor was deformed and severely deformed. There was no reason why the warp shouldn't be powered hard, or they were hot and running through a puddle. So I'm not sure how it started. But for their cost, I'll take one for half the price and at least with the best guarantee of only 90 days if it starts to warp.
