Product review (5 stars): Using to control mini fridge for dry ageing beef
Just got this controller to control the fluctuations in temperatures I was getting with my new Danby 1.7cu ft. Mini fridge for dry ageing meat. I could not get the mini fridge to maintain an even temp between 34-38 deg. No matter how much I fussed with its dial. I hooked this up, and wammo bammo...I am seeing the little fridge right where I want it! So far, couldn't be happier! Set the little  refrigerators dial to the coldest setting, set the Johnson controller to 35 deg...and for the last few hours it has maintained perfectly. I have $200.00 worth of prime rib roast in there for 30-45 days to dry age, and keeping the temps where I want it is super important. So far, I am impressed.
