This spirit level is great, super accurate! When creating art, I often add a final layer of resin. In order for the resin in your painting to stay level and not run off to one side, it is very important that you start your work level. I used this digital spirit level in my art raised by the mugs and the reading was right on zero meaning it didn't go down in any way. I was able to pour resin into this piece of art knowing it would be perfect cone and it came out.
