## Customer Reviews

### ⭐⭐⭐⭐⭐ A brilliant solution where hot water needed in confined space
*by M***Y on 28 August 2018*

REally great, tiny, product which delivers hot water for handwashing. I was sceptical at first, but all fears were washed away as soon as I connected and fired it up. Superb.

### ⭐ Unable to use product - make sure you have the right type of tap before purchasing.
*by S***E on 5 November 2018*

I purchased this product and asked a plumber to fit it for me. My plumber said that the unit can only be used with a pressurized tab not a standard tap. I emailed Stiebel Eltron who confirmed that this was the case. Unfortunately it took me such a long time to get a plumber to come around that I can no longer return the product to Amazon so I have wasted my money. Very annoyed as I cannot see any mention of the need for a pressurized tap anywhere in the product description.

### ⭐ Did not heat the water
*by U***K on 24 March 2023*

It worked for 2 minutes and warmed a cupful of water, then nothing.
