“My new favourite tool. Used it to make precise measurements for a 3D printing project. A nice quality product which can be used to take internal, external, step and depth measurements. You can switch between mm and inches and also lock it with a little screw to hold a particular measurement in place. Came with a protective case which is nice. The display did seem to be flashing after not much usage which I believe indicates the included battery was low, however this is no issue as a spare battery is also included in the box.”
