"Installation was effortless. The instructions for the wired thermostat were a breeze to follow. Likewise, fitting the thermostatic valves to replace the original thermostatic control units was dead easy. We've have the Tado system running for a few weeks now and are massively impressed on how well it performs," one happy shopper wrote.

No problems so far and works well," another said. While a third was simple in their praise: "Very useful product for regulating the temperature of radiators."

Another noted: "Does what it says, but to buy additional valve on its own is just really expensive."
