Product review (5 stars): If you have a fridge in your garage, you need this
I'm not the world's best handyman, but I can work out most problems in my house. I'll admit, this intimidated me though. If you read the directions, it looks like you're extracting the innards of your refrigerator to install what looks like a tiny version of one of those emergency blanks, albeit with heating coil attached. However, the overall install took me about 15 minutes, and I only needed an extra hand for about 30 seconds while I placed the sheet in its proper place (needed to hold some wires out of my way). Since I've installed this, I can attest that it does keep your refrigerator running when the temperature dips in your garage. This one's a no-brainer - just buy it, take your time, read the directions closely and match what you see to what they show (I think in most cases, it will be an exact image of what you're looking at in real life).
