I'v got an 18v Milwaukee and have been abusing it for over 7 years. Just getting nicely run in. It's so easy taking wheels off that sometimes I do it just so as to hose the mud off the underside of the car. So well worth having. I like the Milwaukee 18v batteries too. They seem to have used the same battery fitting for years, so they've very interchangeable. Unlike De Walt who changed their fitting a while ago. However, you can get adaptors so as to fit Milwaukee batteries to other brands of cordless power tools, and they don't 'arf go!
