## Customer Reviews

### ⭐ Useless Product
*by A***R on 30 May 2024*

Bought this 4 months ago and only works with low water pressure and only Luke warm it has now stopped working absolutely rubbish

### ⭐⭐⭐⭐⭐ Excellent quality
*by A***S on 3 May 2025*

Brilliant addition to our camper works really well.

### ⭐⭐⭐⭐ Does what it says
*by R***B on 6 July 2023*

It does the trick. Simple 13A UK plug and 1/2" connections. Doesn't try to heat when there's no flow. Has an on/off switch and displays what looks like a reasonable approximation of the output temperature.Always worth doing the maths - I think a lot of people who are disappointed with this kind of thing are expecting a simple replacement for an electric shower. It'll do that (and standard shower hoses are 1/2"), but bear in mind you're looking at a variation on heating a flow of around 2 l/min by around 20 deg C. Worth measuring the shower head output (or seeing what it looks like at 2 l/min), and feeling what a 20 deg rise over supply temperature actually means. Don't open the tap fully and expect a hot shower - it's no substitute for 9kW, but will run off a standard wall plug mains electric supply, which 9kW won't.
