Product review (5 stars): Great T-stat for my mini fridge
Cheap and a works great on my mini fridge.  Like many, I was cautious since a lot of people said that it kept the temp too low but it works great on my mini fridge and keeps beer at a perfect temp.  I suspect people that are having freezing issue don't realize that the tube needs to be attached to the freezer section of the mini fridge which is made up of the evaporator tubes.  So yes, it is calibrated for a freezer but that is how all the thermostats work on all the mini fridges that I have owned.  Also, I have had this for over a year now and it still works great!
