I have both the cave cube and cave temperature controller from Perfect Cheese and they work perfectly! I've installed them in a 27" Delfield 406 commercial under counter refrigerator (about the size of a kegerator, a little more capacity). I replaced the wire shelves with wooden shelves and can age about 85 pounds of cheese in the current configuration. I can easily go up to 115 pound capacity if needed, and more beyond that with a little work. I had the same problem with the cooling coils pulling out the humidity until I placed rolled up paper towels in the inside drip area from the coils. (This is a commercial refrigerator so everything is easily accessible from both the inside and out, but not big on looks.) Now I have the problem of almost too much humidity because the thing is so air tight. (I drilled a hole for the wires vice running through door.) Anyway, highly recommend the Perfect Cheese products and easily turning a refrigerator into a cave. Good luck!
