Customers say
Customers find the thermostat easy to install and set up, and consider it a great replacement with perfect compatibility. However, the functionality receives mixed feedback, with some saying it works like a charm while others report it doesn’t work properly. Moreover, accuracy is a concern as the thermostat is wildly inaccurate, and temperature control issues are reported, with one customer noting it operates 4 to 5 degrees above the set point. Additionally, display brightness and value for money get mixed reviews.
