Rated 1 out of 5 by from Lasted 14 months, then died. Not recommended. Unit installed alongside a new boiler. The unit is very fiddly to set up. Battery life is awful. It actually ran I went away on my holidays in November, so came back to cold house. Now after just 14 months, the receiving unit has died. Boiler engineer out to resolved. I would not recommend. Have gone back to a hard wired room stat. They are reliable.

Rated 2 out of 5 by from poor quality I bought this to replace my old Drayton thermostat which looked similar to this one in appearance however the poor quality was reflected when I tried to program it. I screwed it to wall where the existing one was but the buttons would not function no matter how often I pressed them they were not connecting with panel. I took it off wall and the only way the buttons would work was to press them firmly whilst laying thermostat on hard surface! I wld have taken it back however the electrician said he would probably have to break the plastic surround on the receiver under the boiler in order to get it off again! The thermostat actually works once programmed so I have left it for now and will eventually replace when I start to have trouble with it. Next time I will leave the plastic cover off until I'm sure I will keep the product because the Drayton one also had to be broken to remove casing.
