Given the price I was very pleasantly surprised after the first start. The price / performance ratio predominated clearly in favor of the performance that is uniquely suited for this award. The sander is not designed for everyday use and was, after 10 minutes of continuous use on a metal plate pretty hot, but held until the end of the disc through what's important. For a household in the weekly times a protruding nail or similar to grind, he extends fully. However, due to the cumbersome A-and off to the designated switch, I give the device just four out of five stars because that's really solved very unhappy.
