The thermostat works as intended. No issues. Setup was simple. So far, so good. The original lasted 10 years. Hopefully the replacement will work for the life of the HVAC system.

Timely, easy install, works perfectly!
Product was received right on time and works perfectly. It was easy to install. Seller also provided option of a "rebate" for returning my old thermostat for refurbishing or recycling. I am thrilled!
