Review on 📏 75x25x15 Measuring Instruments - Visual Guide and Instructions by Joe Meyer

Excellent product. Super clear (new) and fairly strong magnets. Really useful for creating offset parallel lines. It's also useful for measuring straight up and down from a point your spirit level would normally cover. Level measurements are great because you don't need to use a tape measure along with the spirit level. The only downside is that it only measures in metric units and has no millimeter markings.
