Product review (5 stars): If your fridge is in a colder location, this is a must have!
Had issues with items not freezing in garage fridge for years. Basically stopped using the freezer on two different units because of this. We live in Michigan and the fridge is in an insulated garage that doesn't drop below freezing temperatures, but never seemed to keep things very cold even in the colder months. After buying this, the freezer works great. No complaints. Definitely did the trick. If I had known about this earlier, probably would still have the other fridge we got rid of because it wouldn't freeze anything and thought it was just because it was a cheap fridge.
