Like it but While I understand the creator's point re calibration being done by the side  rather than the traditional method for digital levels of first calibrating facing one way  then the other  and automatically averaging  as far as I can understand it the current by-the-side method would only work if you had... a level. Gee. So right now I'm going to go to the basement and try to calibrate it with a level  and hope that it maintains its calibration over time. Other than that I think it's marvelous!
