MAXKOSKO Freeze Thermostatically Controlled Outlet，Automatically Turn On Below 38 °F and Off Over 50 °F

This is an excellent value, saves me time every day when it’s cold. It is super easy to use, just plug it in! Solid feel and has function ed perfectly during this winter. I’m pleased with its accuracy and durability. I use it in my chicken coop for their heater and found it to be very reliable.

These have worked totally as advertised. Were packaged well and shipped pronto!

Works well

It’s working so far. It did not work when I first plugged it in in the cold, but that was because I had brought it from inside and the circuitry was room temperature. I put it in the freezer for a few minutes and then plugged it in outdoors and it worked fine. You can’t just take it from indoors to the cold - it won’t work until it has time to get cold all the way through.

Works perfectly and WAY better price than at the Big Box stores!!

I purchased this to turn on a heater in my pump house when it got near freezing! I checked on it today. The pump house is 49 degrees and the switch is active with the heater running! It should turn on below 38 and off the same. Im sure nothing is going to freeze if the switch is still on at almost 50!!!!! Waste of my money. Another fine Chinese engineered Amazon product!!!!

Just what I thought about it.... Good delivery

Works great with a heated water hose . Turns off the electric supply when temperature rises and turns on the electric supply when temperatures drop .

Je suis très satisfait

Great for you vehicle plug in, bird bath warmers, waterpipe heat tapes and greenhouse supplementary heaters - just to name a few places I have used these. They are convenient for me as I don't want to get up in the middle of the night when the temperature drops unexpectedly.

I don’t have to keep checking the temperature and adjust the heater as needed. I can rely on the gadget to do so for me now.

I tested the thermostatic controller in my garage. The ambient temperature was approx. -7 C. After allowing the controller to cycle several times, the controller would turn on at between 2.9 C and 3.2 C. It switched off at 6.4 C. The controller's performance may be closer to the 3 C (on) and 10 C (off) under different test conditions; however, it appears to operate reliably.
