Should have bought earlier! I have a Steelex precision square, as well as other tools including a Mitsutoyo digital caliper, but I'm still 0.2Β° off for the table saw. This simplifies the process, and the magnet built into the device (quite strong, by the way) allowed me to calibrate different surfaces. And it works really really well. Storage is easy and certainly so small, and using a single AAA battery (as always with rechargeable batteries) doesn't require the purchase of a less commonly used battery. It's half a degree. Of course it won't always replace a long level or depending on the application but if you have this traditional level as a laser level I think you will make things nice and smooth every time. A must for woodworking tools!
