Query: depth slips in use

I'm not sure what the other people doing reviews are using this router for, but it must be stuff that requires zero accuracy. The depth of cut will slip deeper as you use the router, and can really mess up the work you're routing. Perhaps that's why they're selling so cheap... I've tightened the locking clip to the point that the base won't hardly move at all, and it will still slip if I don't constantly monitor it. I'm very disappointed with this Bosch product, which is a new thing for me.
