    Worth buying
  

*by P***L on Reviewed in the United Kingdom on 21 October 2015*

very good for the price from a good manufacturer. This replaces one that lasted for over 10 years and was getting tired

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Good replacement switch
  

*by M***C on Reviewed in the United Kingdom on 8 June 2017*

Thermostat looks good, easy to fit...internals a little bit flimsy looking, but does the job ok. (Ideally you need a live and neutral power supply as well as a switch wire).

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars
