Product review (3 stars): Tiny watch battery only lasts 6 months.
Pros:
Very accurate compared to the two others I have in the room, especially considering the price.
Large and easy to read.

Cons:
Battery died in 6 months.  It takes a non standard size watch battery which I don't have on hand and would have to special order.  Tracking down some tiny battery that's only going to last 6 months anyway just isn't worth the time.

I'd recommend a thermometer that takes AA unless you specifically need something this thin.
