I bought this one recently when the one I had quit working properly. Typically, they have to be replaced every few years for one reason or another.

BIFL? no idea, probably not. But it works well, has a tracking app for your phone that is great, and according to reviews it is one of few that is actually consistently accurate. I like it.
