Product review (5 stars): Awesome to have
Awesome to have, would highly recommend!  It really helps to tell the temp ESP when your temp likes higher ones, and you have kids you have to make sure are comfy.  I can tolerate 86 well while my son doesn't much like over 72 he is a warm blooded kid.  So it's helpful.  Also, with a fieldstone foundation it's necessary to keep the health of the whole home, I bought 4!
