Product review (5 stars): Yep, it works.
I turned a stand up freezer into a beer fridge with this bad boy. It's awesome. I drilled a hole in the side and ran the bulb through it. Plug the freezer into this and then plug this into the outlet. Easy. I put a thermometer in there and tune it accordingly. I will say though that when you turn a freezer into a fridge it makes a lot of condensation inside for some reason. I'm sure someone smart about ACs could explain but if it's happened to both my brother's and mine.
