Product review (5 stars): Small and cheap!
These small thermometers are neat.  We've bought a few recently - we keep one in the freezer and in the fridge.  We also carry one on airplanes - it's smaller than a car key fob - and we use it to show the attendant when it's too hot on the plane.
The first one is about 6 months old - no quality issues at all.
They only show the Celsius scale.
