## Customer Reviews

### ⭐ O rings
*by G***  on November 26, 2023*

O rings are advertised as 4.5” after ordering & receiving, I found o rings to be closer to 5.5” which is nowhere near what I was expected.However return & refund were easy & quick.

### ⭐⭐⭐⭐ Works in my 10" filter, but too much for one
*by R***J on November 23, 2022*

Too expensive for just one piece.

### ⭐ Not really 4.5"
*by  ***1 on October 27, 2023*

These o rings don't fit the aquasana filters, which are a true 4.5" not sure what these o rings are meant for but if you have an aquasana system, these are the wrong ones.
