Excellent.

### ⭐⭐⭐⭐ Excellent room thermostat! Easy to use!
*by N***E on 27 December 2025*

It can be a little confusing if you don't realise that there needs to be at least 1 degree difference between the current room temperature and the selected setting before the boiler will be instructed to turn on the heating. Otherwise it works really well. The numbers are big enough to see and changing the temperature setting in 0.5 degree steps, using the big rotary dial is simple.
