## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by M***U on 17 January 2026*

Really easy to fit only time will tell if they save me water

### ⭐⭐⭐⭐⭐ Recommend this product
*by N***Y on 1 December 2025*

This great! I recommend this product. I’m happy for this, make such a difference on my tap.

### ⭐⭐⭐⭐ Fits well but make sure to use plumbing tape too
*by A***R on 5 March 2024*

Fits my tap perfectly but even tightening the thread as much as possible didn't stop a small squirt of water with a mind of its own. I fitted the aerator and in my excitement turned it on full blast and a wayward stream soaked my girlfriend who was stood next to me. I found it hilarious but she was not impressed, so had to get the plumbing tape out. It works as it should now
