Review on 📏 Magnetic Protractor Inclinometer with Backlight for Accurate Horizontal Measurements by Julian Davidson

I like that this thing has a magnetic base and a spirit level at the top. The magnet is good and strong. It also has a null function so you can use it on uneven ground (like a portable table saw) and then measure the ideal 45 degree blade angle. User friendliness; Has its own carry case. No regret. Update 11/28/2021: Stored for months without batteries. Today I went to use the level. I put new batteries in the device, but it won't turn on. The return window is closed. Very disappointed with the short lifespan. Downgraded the rating from 5 to 1 star.
