Review on Ultimate Magnetic Waterproof Measurements Leveling Tool: XpertMatic Delivers Superior Accuracy by Gary Lucas

I love having an analog level and digital goniometer in one handheld. The battery compartment is sealed, sawdust will not fly into it, and the magnet is very strong. The best feature by far is the screen, it lights up and rotates right side up so I don't have to try to read it upside down. It's noticeably more accurate than removing marks on my saw, and I don't have to worry about removing dust every time I change the angle.
