I shopped around and actually purchased different bands of thermostats. I was not satisfied with the prior products. I thought they were made not to my standards. I finally saved enough money to buy the T6 thermostat. This T6 is made with a good quality of materials. Programming is just as easy as the other completion but, the features on the T6 was better than the previous thermostats that I had bought. With thermostats that control a home I have to be selective and buy the best to fulfill my needs. The T6 did this.
