Works as advertised.Exactly the same as the other colors, with one AAA battery included, not two. This item is presented as a "2 Pack battery tester", which could imply that it's either two testers, or two batteries. Not clear which one. Let me clear this up: it's neither. It's one tester, and one battery to power the tester.The gray color is a dollar cheaper, so check all colors before ordering.
