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. 18-Nov-2016 Product:
