Review on 🧲 Advanced Precision Bubble Horizontal Magnetometer 521815Mm: Enhanced Research and Measurement Capabilities by Rob Bishop

Magnetized very cheaply made. I fixed it to the side of the table and after a few days the spirit level fell off the magnet, it's just held on by a piece of white tape, not glue. The strength of the magnet is also disappointing. It's not worth the premium price for how cheap it is.
