Not much better than eyeballing it.
on April 28, 2013
I bought this to simplify taking panoramas. I think this product is useless for that purpose, here's why:
1) It fails the classic level test for the horizontal (roll) bubble. If you put this in your hot shoe, make it level, and then pop it out and put it in the other way, the reading changes. It is bad enough that it can go from inside the lines to sticking out of the lines.
2) The pitch bubble can't even be tested, because the entire block rocks in the hot shoe. The top surface of the hot shoe foot is a bit domed (convex) because of the molding marks. If they had ensured that the top surface would be concave, so that the hot shoe touches only two points, it would at least have repeatable measurements (if not entirely accurate).
3) Even resting it on the cube faces fails the classic level test. It is common for one of the bubbles to go from touching the right/top marker and after rotating 180 degrees, it is touching the left/bottom marker. This is true for each face.
4) I would guess that the accuracy of this level is about ±1°, which is not saying much, when a common builder's level is ±0.0005°. You will get better results just by looking through the viewfinder and manually aligning a horizontal or vertical reference. If you are trying to use this to level your tripod legs for a sweeping panorama, forget it.
