For the price a brand unit is a real good buy. Due to the wattage and the disk size is probably clear to everyone that the device is not intended for the cutting of steel beams or cut granite slabs. For longer duration of use, it is in my opinion not to be worn. There is handy and I can work with it with just one hand. It also has a good weight, so that you can keep it great in all positions. Only the on-off switch has not been able, I think about him fumbling for and would have preferred a simple toggle switch. But I am satisfied with the small grinder and can recommend it for DIY etc..
