To be honest this Dremmel is one of the best you can buy. I used this on a fiberglass overhaul on an early 70's sailboat (very heavily laid fiberglass). I've used this for cleaning welds and making small cuts in steel at a metal shop where we build and repair farm equipment to harvest and grind cranberry swamps (yes I'm from Massachusetts and no you can use this Dremmel not officially received). USA, manufacturer warranty void but I can't imagine this thing breaking unless you actively try) and I've used this dremmel for fine sanding mahogany. and cherry shape for several other boat interiors. It is great. Excellent battery life, well balanced and comfortable to the touch, it's just a great multi-purpose tool. I can't understand why Bosch isn't officially introducing this item to the North American market, but I'm glad I got it anyway.
