Rated 4 out of 5Â by Candoabitofmoststuff Easy Install, but...
Bought to replace an old rotary dial unit.
Easy install, but instructions, both for installation and use, are not as clear as they might be... and diagrams showing options for how to use it are not labelled and so FAR from clear...
However, anyone competent and confident enough to consider doing their own installing should not really have a problem...
I've only had it a couple of days so don't feel I can reliably comment on performance or reliability yet, (so I've given 3 for both), though it seems to just work so no reason to have doubts.
The one thing I'd consider a failing is that there is no backlight on the display. Where we have it located is rather in shadow, so it's a little difficult to read what the display is showing without some lighting.

Rated 5 out of 5 Excellent thermostat
My caravan room-heater thermostat froze in the ON position. To replace it was going to be VERY expensive. I decided to fit the Honeywell DT90E instead. Brilliant move. Much cheaper and much better temperature control.

Rated 5 out of 5Â by Butterman Great money savers!
I bought on the basis of previous reviews and have NOT been let down!
Installation was easy picking up the switched live and neutral from the original stat. The unit holds the temperature of the house very well. It appears to sense when the temperature is falling and cuts in ahead of the set temperature and in the reverse direction on the rise it cuts out ahead and so you get a very precise result.
I have set the default Eco temperature higher than the standard value so that if we have visitors, we can press the button and override the normal value and have a warmer house for an hour or a greater time if we wish.
