These are great. The slide square is fantastic, and I like that the speed square is metal. But there is one small issue with it, the detents for the measurements extend to the end of the face of the ruler. So if you try to make a fine line measurement you end up with a slightly bumpy line. It鈥檚 not a big deal, but if the ruler face was machined flat(like more expensive units) there would be no issue. At this price point though, you can鈥檛 beat it. I鈥檇 buy it again.
