Not sure how many km's but 3 years so probably around 15k per year, so a few. It still holds for a little while after it shut off, not like it did before though.

This FPR and many like it had an issue where the ball didn't seat quite right and new from the factory they wouldn't hold pressure for more than a minute. I took it apart and used some lapping compound to make it seat properly and it would hold for a good 15-30 minutes afterwards.

I could have got it cheaper in the US, but I know Ziggy would get it to me quicker.
