A great, reliable, easy-to-use temperature controller.
This temperature controller has worked very well in my chicken coop. I love the dials for setting the temperature – they are faster than using buttons. The thermocouple is very sensitive and works consistently. The settings work for heating or for cooling. I use this at night to turn on brooder lamps for my chicks. Currently, it is set to turn on at 80 degrees and shut off at 84 degrees. Super easy to set and read, it helps keep my Dixie Chicks warm and cozy and allows me to sleep through the night. I am very happy with this purchase.

Great combination of quality, functionality and cost.
Works as advertised. An inexpensive yet well built, straightforward device that let’s you control both heating (early spring) and cooling (late spring) of a greenhouse. I especially appreciate how intuitive it is to set up and adjust compared to other brands. No need to save the instructions.My only suggestion would be a brighter display. On a sunny day is hard to see even on the bright setting. I have to shield the light with my hands to see the smaller numbers when setting the temperature range.

Quality and easy function
Use it to control fan on my smoker to keep the temp in check . Worked out great and much cheaper than most controllers. Very good quality. Holds the temperature right where I want it.

Easy to use.
Easy to program. Hold setting after a loss of power. Can be mounted to a wall about 3ft from duplex. Output cord is a bit longer. I have 2 of them. They are with in 1.2 degrees of each other.

Set it & Forget It!
Lovely device. I use this device to 1. Keep an eye on the chicken coop’s temperature. 2. For heating or cooling purposes, because our coop is pretty big, but it has a metal roof and insulation. It tends to get warm real quick and stay warm. 3.Easy to set it unlike my automatic coop door. I don’t need a degree to understand it or jump through hoops to set it unlike our cameras outside. This device keeps the younger pullets warm without worrying about overheating the older chicken. I love this device so much! It’s made my life so much easier!
