If you put them on a flat surface that stays flat, they stay. If you tip it, they will slide off. One of the four didn't show the level accurately, it was a blister. I plan on sticking a real magnet on one of them to keep it safe. Use one in my excavator on a solid surface and throw away the bad one. Still worth the money, just not as good as I was hoping.
