This battery tester has already paid for itself. If a toy (or electronic gadget) is running slow, I remove and test all the batteries. Each time I found that some of the batteries still had 80% life in them, while others were dead. Before I had this tester, I would replace all the batteries. Now I can replace only the dead ones. It is great! It is easy to use and very accurate. It's a great way to save money and prevent waste! Great product! I highly recommend this http://soctester.com for consumers and professionals alike.
