I have had 3 of these in 2 homes for 5 years. After installation which was a little but not terrible work for me to do myself, they have worked well. I also have an Carrier Infinity remote thermostat which is more colorful and has more options - and I have thought repeatedly of replacing it with a T6 as the T6 works more intuitively both on the wall and via the app. I understand the WiFi issues reported by others but have had no issues myself. I have recommended this thermostat to others.
