THIS magnetic measure is a game-changer for my workshop. It`s incredibly easy to use and provides accurate measurements with its magnetic properties. As my tests showed, it's ideal for measuring metal surfaces, making it a must-have tool for any industrial and scientific environment .The compact size is perfect for storing and carrying around making it a convenient addition to my toolset. The only downside is that it doesn't work on non-metallic surfaces. Overall, I would highly recommend this product to anyone in need of precise and efficient dimensional measurement..
