Just received my iGAGING Angle Cube. Looks well-made and the included screwdriver is a nice touch. I’ll take it to work and evaluate the claimed specifications on Monday (to satisfy my personal curiosity).
I did find, however, that the battery included with the gage did not properly fit the compartment. It was an extremely tight fit and my perception was that there was potential to distort the base and top surfaces. It also protruded above the back such that the backplate would not fit.
I had some 9V batteries on hand and tried an Energizer, which fit just fine. The substandard batery was definitely oversized.
