Review on 🔵 Precision 10 Pack Bubble Spirit Level Degree Mark- 10x6mm Circular Bullseye Level for Tripods, Phonographs, and Turntables by Jennings Ford

I mainly use LevelMatePRO; However, I needed an "old school" backup level to check that my camper trailer was level. It was also a replacement for a previous model with an adhesive backing that had fallen off the trailer. I just lay this on the frame to check the level side to side and then front to back. I didn't screw it into the frame or use glue. Just plug it in, check it out, take it off and put it in the tool bag. I want it to be magnetic but it doesn't have to be.
