Great tap and lots of fun for kids to use it
Installed and so far working great. I think it will definitely save on water use. Kids absolutely love it. As you don’t touch it at all it’s always clean.

Very Disappointed
The battery came for about 11 months and since then i have changed 4 batteries in the past one month. I ordered grohe battery from amazon paying about £32 still runs for a week or two and stops. I am left with no option but to change the tap now. Not to forget all the running around and wait times before i can get a plumber to do the job!! My bathroom is without a tap now!

Good but not suitable for every situation
Nice looking tap. Very light and no hint of brass in it. Works well however I would say this is fine in say a cloakroom where the amount of water used is small. I would not put this on a main bathroom sink as the period of time it is activated to produce water is far too short. Using on where you brush your teeth would be tedious.

Great as described
Great product as described though support is very slow eventually Amazon intervene and solve the issue

Expensive for a plastic tap!!!!
Returned this item due to the fact that it was made out of plastic. I sourced an alternative made from brass and home plated that was much more to my liking. In my opinion this item is well over priced for what you are getting hence 2 stars

Entirely made of plastic and expensive
I didn't pay full price for this as I got it from the Amazon Warehouse. Otherwise it wouId have gone straight back. TBH I think it is massively overpriced. It's entirely made from plastic, absolutely no metal in the tap (other than the fixing plate). The flexi tails can't be replaced and they are very short. In addition to this the tails are not a standard UK size so you'll need to buy adapters. Finally, as the whole thing is made of plastic it can be hard when mounting it to get it fully upright. As you tighten the base, so it can't twist, you have to be careful as it can lean backwards as the plastic base bends.

It worked fine for 7-8 months, now the battery is not working anymore unlike the promised number of years.

Después de varios meses de uso, en una zona con muchísima cal en el agua, el cromado sigue como el primer día. Al no tener que tocarlo con las manos mojadas para cerrar, el grifo no se mancha. El aireador es bastante bueno y el consumo de agua disminuye mucho, sumado a que hasta que no se acercan las manos no comienza a salir agua y se evita el desperdicio de esta. Para limpiarlo se puede bloquear el sistema a través del sensor que lleva y evitar que salga agua. Muy contento y recomendable 100%
