I had another digital level that is no longer made and it became very sensitive and difficult to read. (Ok, I borrowed it and it came back with a cement film on the LED.) It works really well. My only complaint (not blaming her) is that she throws an error if you put her on her back. That means you need to have a flat bottom on the surface to be tested. Sometimes it can be difficult in the sun or on the ground. This "feature" was not in my old level.
