Good spirit level well made nice big bubbles for you to see. The magnet is strong. I am an electrician. So when you bend a pipe, it works well because you can adjust the number of degrees on the spirit level to bend the right angle. The best level I've ever had. I had a Klein Craftman checkpoint and after a while these values dropped a bit. This level is well built. I'm a little pricey but you get what you pay for at this level
