It's ok - a budget item. Not keen on the mounting plate - if it's screwed flush against the wall then getting the thermostat onto it can be tricky. Have taken to padding behind the top of the plate to bring it away from the wall a couple of mm. Makes fitting the thermostat much easier.

The wiring diagram within the product isn't as clear as other Heatmiser thermostats. By going on line and looking at other products installation guides then all became clear.

I have looked around and could have bought cheaper but nonetheless the product is working so far.
