## Customer Reviews

### ⭐⭐⭐⭐⭐ Vaillant Prv
*by R***R on 10 December 2023*

Works

### ⭐⭐⭐⭐ Does the job, looks sturdy, be aware clips are not provided
*by D***S on 31 January 2024*

Does the job, looks sturdy, taking a star only because on the picture it has the clips, but they are not part of the product, which is misleading. I reused the existing clip that was in good contigion

### ⭐⭐⭐⭐⭐ Eco price.
*by A***S on 1 June 2021*

I am sure could have refurbished the old one but not worth the gamble for the price. Easily changed.
