Product review (4 stars): Nice enough
Positives, you get to see up to 4 temperature readings from three other sensors.

I took off a star for because you are not able to switch displays on the indoor units.  The only unit you are able to see other temps is on the main unit.  Being in a two story house, this is not what I wanted, I want to be able to see temps from outside and different levels of my house in multiple locations, this unit does not do that.  It may have been my misinterpretation of the wording on the indoor units being able to "Change Channels" that led to my issue, so I only took one star for not clearly stating the only unit you can see other sensor temps on is the main unit.

Temps seem to report accurately, and other than not being able to see other sensor data, the unit works fine.
