I hope I just don't understand how to use this level. I put it on a fairly flat surface and the bubble fell all the way to the right. So I changed the orientation to 180 degrees and the bubble moved all the way to the left. I could be wrong but I thought the bubble would be centered between the lines if the layer is on a flat surface. No matter what orientation I set the spirit level, the bubble always settles at the same end of the spirit level. I think if you attached a level to something you could route it somehow. I'm sorry if I'm wrong, but if I'm not then I'm a little worried about how something like this could pass quality control and be shipped from the company.
