Review on 🔋 Enhance Efficiency with the DAOKI Universal Button Battery Checker by Christopher Smith

This is a handy little gadget for when you're tired of batteries lying around that may no longer be usable. My only small issue is that it's a bit difficult to "balance" the batteries so that the pins on either end are in the correct position to measure the remaining charge in the battery. However, you get used to it pretty quickly and it saves me a lot of trouble trying to figure out which batteries are "dead" before trying to use them. Good value for money.
