Have had my old battery-powered drill (Stihl) for many years now but when I came to get a new battery I found they no longer make them for that model. So bought this as a replacement. Wow, absolutely fantastic, how these things have moved on. Have used it now for a couple of months and it has passed the test with flying colours. Have just moved house so there was a lot to do and this drill showed its versatility. No, worrying about charging the battery the right way, I've only charged it once and it's still going strong after a lot of use. Hammer drill and screw driver modes work superbly well, there's a light that shines on the working area, the charging system also lights showing how much charge there is left. All in all highly recommended.
