Review title: Good gizmo
Product review: I have two of these things, and they work just like the advertising says they will. The quality is good, they are easy to install, and they will solve some of those vexing battery problems that you wonder about. Such as: is the battery reaching the end of it's life? Should I replace it before I get stranded? Stuff like that.
