I've been using the device about 1 hour ground once a metal railing, 30min created a metal table and a few wall slots for cables. With the performance of the unit I am satisfied, it is the demands of home work adequately. First, I would have liked a speed control, but then you need the rare but for everyday work, and then for the double issue? Packaging is unfortunately only cardboard, but that's with the price ok. The partially criticized on switch I can not complain, this is the switch, which holds the disk when moving, rather stiff. The guide is very concise for someone who has never worked with an angle grinder. But that's all small stuff, all in all, a good device, which looks solid and even has a pleasant long power cord.
