Review on 🔢 HOMREE LCD Digital Tally Counter: Shockproof 5-Digit Battery Powered Counter Panel Gauge for Precise Counting by Michael Weaver

so no instructions included, but the two sets of screws on the back have markings. One set is for the magnetic switch (50/50 chance of getting it right on the first try). The other set says reset and it's just instant contact to reset the device. The rest of the device works great. oh, and it holds a charge even after you remove the battery. However, you must replace it in order to use it. LOL This thing just won't turn off, but it's been a month now and it's still working. I recommend if you want to wind coils.
