### ⭐⭐ Backflow protectors don’t seal well
*by C***L on 24 August 2023*

The duckbills work alright, but the backflow protectors don’t close together very well and so the back piece that attaches to the tubing pops off a lot.

### ⭐⭐⭐⭐⭐ Very handy
*by N***E on 17 December 2025*

These are great and handy to have the backflow protectors as spares when my others are dirty, the valves are also of great quality.
