Works great! ordered 2 extra transmitters with it. One is in my greenhouse, one is in my chicken barn with the new chicks. The low temp alarm saved my greenhouse as it let me know that the heater had stopped working. Saved my weeks of work with the seedlings from being lost to the freezing temps.
I hope this product lasts as well as it works because I am loving it so far!

ordered this unit with two extra transmitters...only two of the three send a signal to the receiver. I contacted the company with no response...the two that do work seem to be fairly accurate.
