Hi Tim how are you?
I'm 29 years old with an On-X valve and would love to discuss and share with you my experience until now.

Hello Harris,
I am just turning 50 this year and have had an On-X for 2 yrs. I was pretty young for a valve replacement, but you have me beat by 20 years! Sure, I am happy to discuss the experience with you.
My best.
