I had to return my level as the main reason for buying it was to use it on vertical surfaces. I couldn't calibrate the level on a vertical surface and the reading was 0.45 degrees when rotated from one direction to the other. This difference was more than I needed based on the application I was using it for. Note that the bubble in the level indicator was in the same position in both directions, but the value displayed was not.
