I totally forgot there were discount codes for this. Glad I didn't actually miss out! Got my controller a few days ago (from Amazon). Works MUCH better at maintaining the temp in my kegerator than the stock controller, needless to say.
How do people usually attach these to kegerators? It works well, but the logistics seem a little awkward. I'd hang it on the wall behind it, but then I can't pull out the kegerator for maintenance, CO swaps etc. since the cords aren't very long.
You could use one of those 3M stick on hook things. Or velcro
