I have used a level like this before, at work. Today it was my time to purchase mine! Love the magnetic side of this level. Dewalt yellow, it doesn't blend in with the rest of the stuff at the job site. Large. 4 feet large. I wont get false level readings with this big ol' level. Really happy with my purchase! You will be too if ya get one. Only drawback is its a little on the expensive side.
