## Customer Reviews

### ⭐⭐⭐⭐⭐ The way of the future
*by A***R on July 18, 2024*

First, these are made in the UK, which is fantastic. Second, they are quite a bit faster and easier to work with than sharkbite fittings (actually made by the same company, RWC), particularly when it comes time to remove them. Beware if you run PEX with them you will need to use the inserts, which are easy to find although I am not sure if amazon stocks them.

### ⭐⭐⭐ Looks like a nice product
*by H***1 on July 6, 2024*

Does not fit on RV water lines.
