Better than all the other cheap ones this one gives you a level read out to let you know how much juice is left. Not just a good poor and bad.

I was very disappointed in this item, especially that it needed a battery in it to work. Having a small box full of batteries to test, many in their original packaging, I truely question the accuracy of the item as many of them did not register. Our first battery tester that was bought from a Walter Drake catalog and for less money (but was lost), was better.
