Negative Positive
Title: A little pricey, but works great.
Review: I compared this to my old low price tester on a batch of used batteries. There is no doubt the MTB works MUCH better. I was hanging on to these batteries because the old tester was showing them good, but they wouldn't run toys. The MTB shows how much battery is remaining. I recommend you test a battery twice to confirm the reading in case you were not touching the contacts well the first time. My only complaint is that the method of contact is somewhat annoying, but is a minor inconvenience; after all, how often do you test batteries anyway?
Is the review positive or negative?
