There are a few Milwaukee owners on the forum according to a poll from a few years back. The only thing I ever heard bad about them (the routers, not the owners) was a few owners stripping a fiber or plastic gear used in the height adjustment. This could have easily been a user mistake, as in trying to adjust the router while still locked or not cleaning it if it got sticky. Otherwise they have been a very quiet lot which is normally a very good sign. I suspect there would be more Milwaukee owners if not for the price of them. That is the only reason I never bought one. They tend to be pricey and sales seem to be rare with them.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
