Product review (5 stars): perfect!
Our garage frig recently started swinging from freezing to warm temps.  After calling to see what a repair person would charge and finding out just the trip charge would be $50-100, I went online and googled the situation.
The consensus seemed to be that one of two likely repairs were needed.  I felt the thermostat was most likely so I then googled our frig model, found the part, shopped for price (yeah amazon), and had it in my hands in two days.
Husband said it was a very easy repair and now our frig is backing to working well.
