KT121 inline Thermostat

Purchased this to control a forced air kerosene heater in a garage which had no temperature control. It works as it should, cycling the heater on and off to maintain the selected temperature. No more manual plugging and unplugging the heater to keep warm.

I would purchase this item again.

Set this thermostat up in our greenhouse to regulate the a/c. It works great. Thanks for making a quality product.

Well made

Have only been using the product for a short while but, it seems to be working as I had hoped. It is well built and quite sturdy. Would recommend it for sure. Can't give it five stars yet, haven't had it long enough. I feel it is going to stand up to continuous use quite well. Will see.

My chickens are happy.

Works great and simple to use. Could use a better mounting means. The flimsy wire hook is no match for the heavy duty cord. Overall a great solution for basic temperature control.

Works fine.

Works fine for me to keep root cellar from freezing. Takes some adjusting, but once set, works as I hoped.
