I've had an old old old ear thermometer and it quit working the other day, I recently purchased a $10 one that is for your temple. I thought it would be good, but it being $10 made me kinda worried that it wouldn't. It worked for a whole two days, said the battery was low. I replaced them with brand new batteries and still said low and shut off. I need to know a good one to buy for my daughter. Preferably an ear thermometer, I don't care about price. Just one that is going to be as accurate as possible and won't quit working when I need it!
