Review: Low cost alternative to 'proper' smart valves - Easy to fit and work well. Instructions are fine if you follow carefully. These are programmable (time and temperature) rather than smart. I'm using them alongside connected/smart thermostats for some of the radiators, especially where I had two smart valves on different radiators in the same room which were fighting each other.
Review: Avoid at all costs, better options out there. - These are terrible. They are my fourth variant of smart TRVs so I'm fairly accustomed how to program them. These are a different beast and not at all user friendly. Also almost impossible to calibrate. I set one room to 30 and the radiator remains freezing cold, another to 15 and it's constantly on. Absolute disaster. Hard to install, don't work, avoid.

### ⭐⭐⭐⭐⭐ Low cost alternative to 'proper' smart valves
*by M***N on 14 December 2025*

Easy to fit and work well. Instructions are fine if you follow carefully. These are programmable (time and temperature) rather than smart. I'm using them alongside connected/smart thermostats for some of the radiators, especially where I had two smart valves on different radiators in the same room which were fighting each other.

### ⭐ Avoid at all costs, better options out there.
*by M***L on 26 October 2025*

These are terrible. They are my fourth variant of smart TRVs so I'm fairly accustomed how to program them. These are a different beast and not at all user friendly. Also almost impossible to calibrate. I set one room to 30 and the radiator remains freezing cold, another to 15 and it's constantly on. Absolute disaster. Hard to install, don't work, avoid.

### ⭐⭐⭐ Could have had 5 stars
*by C***M on 25 November 2025*

I purchased six of these TRVs (three packs of two on a Black Friday deal) for fitting to my central heating radiators so that I could see the actual room temperature that each was set to rather than the 0-5 option of my conventional valves. I didn't want or need a wireless remote connection or boiler remote control and these TRVs fit the bill perfectly at a price point well below that of connected systems. Now installed, they are working well and maintain an accurate temperature in accordance with the digital display. So, why not 5 stars? The reason is the well justified criticism of the user guide/instructions as widely reported by others. There is some better documentation available online than that supplied in the box but even that lacks clarity. Such a shame that this very well made (and performing) device is difficult to recommend due to such appalling documentation.
