What to know before buying
Listing details to confirm
The product is described as wired, while the specification fields also list corded electric power and a requirement for two AA batteries. Confirm the required electrical connection and battery arrangement for this exact model before installation. The listing also calls the controls both touch and button control, and its broader DT3-range compatibility claims may not apply to every installation. Check compatibility with the heating system and wiring.

The available customer evidence is limited to aggregate ratings, which are mixed rather than uniformly positive. This gives only a broad indication of varied experiences and does not explain their causes. Buyers should weigh that uncertainty against their specific needs, especially the wired installation and lack of app-based operation.
