Optimum Duostat RF Room thermostat with Boiler Module is rated 4.8 out of 5 by 4.
Rated 5 out of 5 by from Great value for the money. Gas fitter well impressed by the quality, fitted it in ten minutes, and picked a basic program for us to get used to.

Rated 5 out of 5 by from RF room stat Bought to replace a previous one (lasted 8years) not as easy to use but once you get used to it seems ok hope it will last as long as the other one

Rated 4 out of 5 by from Great value I've got a baxi 80e that's 20 years old and I fitted this in 5 minutes, it goes straight into where the timer was. I'm not convinced it's reading the room temperature correctly though it's easy to adjust the parameters once I've checked the temperature with an air probe. Overall excellent value for money

Rated 5 out of 5 by from Simple Perfect replacement parts. Module was a doddle to fit and wireless controller simple to understand. Only had it a month and not had heating on yet, but test runs worked perfectly. Would recommend without a doubt.
