Intercomp 102144 Digital Angle Gauge with Magnetic Base

I bought this for a diy vehicle alignment so it would save me some time. It arrived on time in seemingly good shape. turns out it is made in China. it also turns out it is not accurate at all. I need about 0.2+/- degrees for my application. this one was off by at least 0.5 degrees. the published spec is +/- 0.2 degrees. Here is the problem. there are magnets on three sides. attach it to a known plumb vertical. set it to zero. flip it 180 (looking top down rotate it one half turn) and reattach to the known plumb vertical in the same place. it now reads between 0.5 and 0.6 degrees. rotate it another 180 degrees to the original position. now it reads zero again. Setting re-calibration was no help at all. I was better off using a string and weight and just doing the math. Ughh... I bought this one because intercomp has a good name and it seemed to be made in the states. It costs about 2x what the cheap Chinese ones cost. I returned it.

This angle cube is essentially the same as other cubes(magnetic base and sides) I own except the readings are illuminated. I sharpen a lot of knives on my Wicked Edge Precision Sharpener and my old angle cube was so difficult to read with these 70 year old eyes. This cube gives a brightly illuminated reading!! How good is that. Thank you Amazon! Once again I found what I wanted with your fine service.I gave my old angle cube away to a young man with sharper eyes than mine.

Used it to set up pinion angle. Worked great.
