Fridge-Fix by Smart RV Products - has anyone installed?

I have one, it was definitely pricey for what it was (and I hadn't seen this thread for the DIY ideas) but it works well and definitely keeps the fridge cooler.

I also noticed that the cool down time is substantially reduced when running with fans over the cooling fins.

Would I buy it again? For the price probably not, I'd DIY. But the concept is great!
