Product review (5 stars): the BEST sensor set I have ever owned
the BEST
I have had many of these temperature sensors over the years, more than I can count.
this is the Best because it was super easy to set up, just put the batteries in and it was ready.  didn't have to pair them to each other or set a clock that I do not want anyway.
it just WORKS GREAT.  does ALL I want it to do.  I am obsessed with knowing outside temp and humidity compared to inside thus purchasing these over the years.
this is the BEST.
