Works good. Love the fact you can read your temps while not actually at the house.
Only thing I don't like is it takes a while to update temps.
I had one sensor in the house at 70 degrees then moved it outside 35 degrees and I did not get my low temperature alarm until about an hour later.  Setup was a little frustrating could have used a little clearer directions.  But all in all its nice would buy again.
