### ⭐⭐⭐⭐⭐ Nice and solid. Not like the plastic ones I had that cracked.
*by H***N on January 2, 2026*

Seems to work as intended. But time will tell.

### ⭐⭐⭐⭐⭐ Simple device -- what could go wrong
*by L***. on June 20, 2025*

Good fit/quality; Good price; Hopefully, the internal rubber valve will last as long as the old one.

### ⭐⭐⭐⭐ Almost perfect
*by T***1 on June 24, 2022*

This product is very well made and easily installed and works as it is supposed to. My only problem with the unit is the set screw twisted right off. So be careful when you lock the screw down and don't apply too much pressure (torque) or you will twist the screw right off.
