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!

Replacement works great, but had to return the first one
I was very disappointed to find out that after all hard work replacing my old tap with this new Grohe it turned out to be faulty. There was no response from the sensor. I even ordered a new battery but it didn't help. So had to return it and ask for a replacement. The new tap came quickly and works fantastic. I also recommend to install the enclosed mesh filters, as the tap tails don't have rubber washers. I also installed 1/2 to 3/8 inch valves instead of adapters. Despite initial setback and disappointment I am very pleased!

There's nothing to touch this
As a trade professional I recently installed this item for a dentists surgery to enable Covid compliance,with its touch free operation It was. Perfect for this situation .

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.

The unit Stopped working :-(
We bought two units for our bathrooms. One of them failed within the first year. So, we were given a replacement. The replaced tap stopped working, within an year of installation. Now, since there is no warranty this is all up in the air :-(. We replaced the battery (Grohe), without any luck. The other unit is still working fine without any issues, though.

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%
