As per the other comments they worked well at first when I eventually got them to work with the range of radiator valves and then with a couple of problems the valves can only be programmed in-place on the valve so you need good eyesight if your valve are placed out of the way as mine, and again when you replace the batteries. All mine have stopped working but this is now well after the quarantine so they don't last as long as standard radiator thermostatic valves.
Oh yes I fitted one to a friends house that had cats and the cat broke it off as it squeezed itself between the control and the radiator.

Rated 5 out of 5Â by NorthDevon Great simple TRV
Needed something to zone off two large bedrooms, one lounge and an ensuite. Setting up was a doddle as well as fitting on my existing Honeywell TRV bodies. Only been a few days but loving the ability to reduce heating oil wastage. Motors make a noise on adjustment but nothing to worry about. Time will tell on savings but happy about not having to walk up three flightsvof stairs to twiddle with manual TRV's.

After wasting about an hour setting it up I soon noticed that the radiator was always on. I therefore gave it the benefit of the doubt, reset it and wasted another hour setting it up again.
Turns out the pin on the devise doesn't compress the valve pin on the rad enough and even when it thinks it is off there is still water flow into the rad and hence the rad is always on!
It is missing some other fairly basic functions, like letting you know what temperature it currently is in the room so you can a just accordingly.
And I wish I'd listened to people about the noise! I installed this in the bedroom and even though I'm a heavy sleeper it woke me up several times in the week before I returned it!

Nice bit of kit but a bit on the large side but thats not a downer. Thought I would try this TRV in my bedroom as I like a warm room in the evening but if theres any heat during the night or early morning it wakes me up - seems to do the timer part perfectly. Its a bit fiddly to set all the timers for different days but once its done thats it and it was a straight swap for the Drayton TRV 4 that was originally fitted. Noise from the motor controlling the valve is barely noticeable so should not be intrusive.
