Honeywell DT90E Digital Room Thermostat + ECO is rated 4.4 out of 5 by 114.
Rated 1 out of 5 by from Waste of money I bought one of these as I thought a digital thermostat would be the way to go. Wrong! This model is supposed to be 'intelligent' but its stupid. Sorry I was going to write whats wrong with it but that would just take too long, in summary just dont buy it!

Rated 4 out of 5 by from Nice and simple. Good product, but instructions for wiring need to be better. If like me you're going from a 3 wire thermostat to this then you don't need to use the blue negative wire, i blanked this off with choc a bloc. Then the normal red live goes to B and the other live ( bit sure what you'd call it but mine is dark red with yellow sleeve on it) goes to A. Hope this helps.

Rated 5 out of 5 by from Honeywell Digital thermostat Bought this to replace my old Honeywell dial thermostat. Simple to fit only needs two wires took about 15 minutes. Displays current room temperature, is more accurate and looks smarter.

Rated 4 out of 5 by from Control at a very good price This stat control is much better than the mechanical ones. It holds the set temperature stable, and is a doddle to change to what setting you are looking for (and is accurate to half a degree!). At this price why pay more?

Thank you Screwfix Cannock excellent pleasant friendly knowledgable and helpful staff :-)
