Product review (5 stars): 8 months and still working fine.
Used this to convert an upright refrigerator into a red wine cooler.  I was at first torn between this and the digital controller which only had a ~$20 difference.  However, I figured that the simpler the unit, the longer it's likely to keep working so I picked this one up.  I used a little bit of easy to remove duct seal putty to fill in the holes to create a sealed environment, also allowing me to rest easy knowing that replacing the temperature controller won't be a chore the 2nd time around.
