This wonderful accessory, for whatever you are working, for whatever needs to be counted and kept rack of! When not in use, the screen goes blank (to sleep) but as soon as you push the large silver button, it awakens, right where you left off, and continues counting. So it has a battery saving mode!
Mechanically jumps with every press, quick reaction.
Reset button clears to zero with one push.
