Query: Good product, thermometer provided is useless !!!

I've used this yogurt maker for over a year, makes very good yogurt, pretty much a flawless process, however the electronic thermometer that wasprovided with the kit is junk. I've gone thru the two batteries provided, and they died within a couple months. Go out and buy a analog thermometer and you'll be much happier.
