Funny that I had to Google to find this in Amazon (I guess stuff that's sold out doesn't come up in the Amazon search) and then when I do I read the "Failed in One Week" review. Well, at least that reviewer got a week out of it. Mine failed in about 3 days. Several different batteries later and I determined that its the unit. Ditto "how much trouble will I go to for a $15 thermometer". Guess its the trash heap for this one.
