Adjustable Height Universal Dual Flush Cistern Valve with Sensor Button. (touchless

This is actually really good and quite easy to fit (as long as you are comfortable working on simple plumbing type projects). Nicely designed (better than a previous similar French design model I have used) and strangely "attractive" in appearance - if a flush button can be such a thing! The overide pushing of the blue button part, if the batteries have failed you for instance, is really well implemented. Happy with the purchase.

Good quality touchless flush mechanism. It operates very quietly and has a fallback that if the batteries are flat, you can push the button in like you would on a normal push button flusher.It works pnumatically (by air tubes) and the touchless mechanism works by running a small air pump for a few seconds to operate the flush mechanism. Once installed this is noise is barely audible and drowned out by the flush itself.The only negative is that despite being "dual flush" the touchless aspect is not dual flush like you'd expect with a manual push button, so it will always use the same volume of water for touchless flushing. I was hoping that holding your hand in front of it would lead to a longer flush, but that's not the case.
