Very powerful little grinder, although rather heavy for its size. I did drop it and the internal mounting point for the power switch broke, which I managed to repair, but I thought it was rather flimsy.
The spark guard it too large,(ie. deep) which restricts accessibility to tight spaces and the quick release for the spark guard gets in the way when using cutting discs. it actually restricts you from using all of the disc. For the price, not a bad unit. I only bought it because of the price and the bearings had gone on my other one. It was easier to buy one at the time than fix the other one. Although, I will be fixing the other one now and the Worx one will be my back up.
