Promising review: “I bought this as a gift for my wife. She is in love with it. It decluttered our junk drawer and made order in our home. It comes with a tester, which is great because we were able to eliminate the bad batteries, which we got rid of, from the good batteries, which are now resting securely and neatly in the organizer. Would I recommend this to a friend? Absolutely. We already did!” —Amazon Customer
