Unit appears to be ok and operational. The build quality is perhaps not the best as the unit I received doesn’t fully 'snap' in to the 2 ball-bearing locking arms on the wall bracket to mount the unit totally secure to the wall. One arm appears to engage and secure 1 side of the unit but the other side appears slightly loose. Discussing with Heater Shop they have provided feedback to the manufacturers on this.

Programming the unit is a bit confusing if you want to use it only as a heated floor thermostat controlled only from a floor mounted sensor. To their credit Heater Shop followed up on this with the manufacturers as well.

Unit arrived quickly but I had some issues with the unit (thermostat) and raised a ticket through their website. Ticket was followed up a bit slower than I would have hoped but once they responded and we discussed they followed up very quickly on all the ssetup/technical points I raised.
