Accuracy is not the highest. Good thing there are 4 of them. I put all 4 side by side on my van's tubular metal bumper. Everyone reads differently. So I got a more accurate level and found that 1 out of 4 is the closest and that's what I put on my van's tongue to use. The magnet doesn't seem that strong, but I took three hours of rides with it before it got stuck on the frame and it's still there. strong enough
