Oops delivery. Protecting plate was broken but the SC AMAZON solved the problem as usual. Although it is not a grinder for professional, it is satisfactory for DIYers. After a few minutes of use, the drum began to vibrate dangerously because of the wheel mounting nuts were loose and brush (note that clamping is in the opposite direction of the clock). For security reasons, you should check the tightness of these nuts before any commissioning. The lamp LED (essential) lights automatically when the grinder is in operation (pity the gooseneck as short). I wonder how I managed to pass me so long with such a device that makes life easier.
