Although I have had a good quality vernier caliper for many years decided to get one as the eyes even with close-up glasses have trouble with the smaller graduations. Works quite well so no complaints. Has on and off buttons of course but you don’t need to actually turn it on, as soon as you open the jaws she turns on.
