Just put it on a tripod, level it, and rotate the tripod head 180
degrees. That should tell you how accurate it is.

My "hot-shoe bubble" was fine. Trouble is my hot shoe itself wasn't
level. I started trusting the little blighter when I first got it
and
only later realised that all my images were a fraction of a degree
out.
Sometimes I wonder if it isn't easier if you leave a *bigger*
adjustment to make in Photoshop.
I don't know what accuracy one can reasonably ask of a simple bullseye
bubble, either. A 4-foot framing level can easily be off a quarter
inch across a 20 foot wall.
