I'm not a great handyman or a purist precision but I try to do things properly. I need time to time to make holes and thus to measure the diameters of the holes or screws. Do not doing it very often, I wanted to make my lazy by taking a digital caliper. I was hesitant because of the price by looking at Facom is 70 min. I use it for 5 times a year it's useless. So I chose this model that's perfect for me. Already it is in a hard plastic protective box and not in a soft case. Then for some uses made, it is clear (maybe not as much a tool 100 or + but it is not even on), there is a button off not to gun down the battery, it is very simple to use and there is a head stack in the box.
