Title: This item is inaccurate
Review: I was very disappointed with this item. I am working on crown molding and thought I would save a few bucks. When I checked this unit against 2 know 90 degree set squares, it was off by 2 degrees. Its essentially useless.I should probably have spent more and got a more professional unit. I'm sending it back, but after postage I'll probably net very little as a refund.
