Customers find the thermostat excellent in quality and easy to set the “on” temperature, with accurate temperature readings. However, they report mixed experiences with temperature control, with some saying it works well while others mention it won’t regulate temperature at all. Moreover, reliability is a concern as some units fail within 6 weeks of use. Additionally, durability receives mixed feedback, with some finding it heavy-duty while others say it doesn’t last long. Compatibility is also problematic, as the thermostat is not recommended for use with window AC units and heat mats.
