Easy to install and the instructions are clear. Added bonus of being able to control via an app. The timer on the heater is only a countdown timer which is ok but for more programming you need the app. The screws that hold the heater to the bracket are a bit fiddly getting back in so you need to make sure the holes are facing up and a bit forward otherwise you can’t tighten them as you can’t get the screwdriver on the heads properly. I bought 6 to replace storage heaters in a rental property I was updating. Seem to be working fine. A good alternative if you do not have access to mains gas.
