The product is excellent. Had a bit of trouble setting it up, probably due to my own issues. A quick call to the technical department fixed it. I'd highly recommend Heatmiser. First class service, and excellent support.

Very (pleasantly) surprised at how easy this was to set up. The Neostats had been installed by a qualified electrician, the hub arrived and it took about 30 mins to connect to my hub, configure and pair with the (6) neostats in my home. I was up and running using the (pretty good) mobile app very quickly and all working smoothly.

The product took a bit of figuring out to set up, as the iPhone app is not totally intuitive. However once figured out, it's not difficult to use and seems to work well. Note we had to buy an extra plug for £40 as our wifi router is not close enough to the thermostat (4m over and one floor up)
