Good product, but the initial set up was a bit glitchy (for me)
Easy to install the RF receiver and no need to remove the internal link
The App is easy to install and set up the thermostat, but the RF receiver did not install straight away. On the second try it said it had not installed, but I pressed the next button and the wireless link connected.
Also when setting the schedule it failed to work. I had missed the step where you associate the schedule with the thermostat (which is in my lounge) as soon as I made this association my schedule kicked in. So not the most intuitive software (but this may be me)
Other than this initial glich it works great so far (only 2 day in)
I also bought the thermostat stand and this looks great
