Title: Stops working if stored improperly
Review: The instructions say it has to be stored upright. If it is stored lying down for more than a day (like, say, if you are sick and can barely reach to put it on your bedside table) the liquid will 'freeze' in place and not move or become fragmented, rendering the thermometer useless. I went through two before wising up. It is also uncomfortably shaped and hard to keep in your mouth. Skip this one.
