I have been a home remodeling general contractor for 20 years. I have used many of the cheaper levels. Stanley, Johnson, Empire. I see complaints that they are thin and light. To be honest, I see that as an advantage in most situations. There are no problems with frames, doors and windows, tiles, plumbing, cabinets. I don't use them for stone work, but that's about it. Super easy to read. super accurate. I personally like them very much.
