## Customer Reviews

### ⭐⭐⭐⭐⭐ Useful
*by D***A on 25 June 2025*

Excellent product for the property where the boiler is located in the attic.No issues to set, easy to use. The most important is that it has no WiFi only radio waves. So you don't need broadband to use it.

### ⭐⭐⭐⭐⭐ Easily fitted by qualified engineer and makes control of central heating extremely easy.
*by P***1 on 4 May 2025*

Fitted by qualified engineer very quickly and works as described. We didn't have a programmable thermostat for our heating and this does the job extremely well. Recommended.

### ⭐⭐⭐⭐ Programming competency
*by H***N on 30 April 2024*

Another reviewer said they packed it into the box and returned the lot. I can understand that. It’s a nightmare, not for the feint hearted. The instructions are limited, and assume some knowledge of the product. After many attempts to get to the 7 day programme I gave up and altered the default settings, laborious but doable.
