    "Best Purchase Decision Ever"

    I had bought two of these last fall and put them in my well houses. I had no frozen pipes all winter. My well house heaters went on and off automatically and the turned off when it was warm enough. I would recommend this to everyone

  2. 5.0 out of 5 stars


    Used device for years. Highly recommend, wise to have a spare on hand just in case; especially if placed in well house where could be damaged by water; I know not a happy thought. Always placed away from heat lamps in well house to avoid thermal stress.

    "Works like a charm"

    Turns on and off according to prescribed temps. Make sure it is used where it will not be exposed to direct elements. Would recommend

    "Really nice"

    This worked great last winter to control the power to heat a K&H outdoor heated bed for an abandoned cat. She loved it and thanked me profusely. She was nice and toasty in the cold weather.

    "Great for milkroom "

    I ordered one of these to plug our milk room heater into so that we weren't needlessly heating it overmuch. It seems to be doing the trick, our electric bill is going down, and my medicines and supplies are staying liquid! The holes are a little tight fitting, and it does take some muscle to get the plugs inserted.

    "worry free"

    I use this to control my heated bucket. I use it during the fall and spring when temperatures vary more and buckets dont always need to be heated (normal winter is always below freezing). Then I dont have to plug and un plug or remember to. Helps me save energy too.

    "Convenent "

    I odered these ThermoCubes to use with the Heated Flat-Back Buckets. They work well and we are pleased to have warm water in the freezing weather without worrying about plugging and unplugging the buckets all the time. It would be nice if they turned off at a lower temperature, but like them all the same. I will be ordering more for other uses.

    This Thermal Cube works great. We use it to turn on heat lamps for our water well house, greenhouse, and doghouse. I am ordering more to use in other areas because you can plug it in and not worry about things freezing. Thanks for making such a great product.
