I have a Lumber wizard I got a while back - it worked for a while but now it doesn't work, and having paid $100 for it I tried to get it fixed... You can search all day and night on the internet, call the numbers on the instructions, the company that makes this is now hiding behind some internet distribution outfit that won't return e-mails or phone calls requesting info on how to get it fixed.Forget it, no after purchase service at all. Very disappointing $100 piece of junk I now own.
