The T6 comes with all homes in this community. I am happy with the builders choice. It is a no brainer to install it in new construction and it probably would pay for it's self in years to come as a replacement upgrade.
The product seems to be good in keeping the temperature where it is set at. The thermostat is difficult to set up by hand, the programs are no explained very well in the directions. Had to go online to set up for separate days and times.
I am very happy with this purchase. When it was first installed with my new furnace my wifi was down so I tried to program it on the unit itself. It did not work very well. Once I was able to download the app on my phone it was a piece of cake (much easier to control the unit on your phone). I have not tried to control the unit from afar, so I can't comment on that.
