We have only been using this product for about a month, but so far so good. I really like the wifi feature. I can control the thermostat when away from home or just laying in bed at night.
I had a little problem pairing to my phone but once it paired all was great. Easy to navigate. I can check temperature status when away and control as needed.
Good thermostat for daily usage. Quirky app installation/connection but once it connects, it is easy to use from anywhere. Not as up-to-date as I would like for technology purposes, but a good upgrade at the house of an elderly woman.
