They tested one of those things in a fairly recent issue of one of the mountian bike magazines. I don't remember which one. I think they gave it zero out of five stars. They calibrated it per the manufacturer's instructions by "zeroing" it out on level ground. As I recall, they said that the bubble is in constant motion and that they buried it on mild to moderate inclines! Hope this helps. Sounds like the thing is a complete joke!
