I have this Pure Energy 1.1L 5,ooo psi preset bottle.
Collected from it's first retest today so it's good for 5 years.
Stamped and complete with the certificate and nipple cover.
Offers around £90 posted..add fees or gift...cheers...
I don't know if this is very helpful, but I might be interested. Currently waiting for my bottle to get tested at h-pac, if it were to fail then almost certainly I'd want to take this off your hands. Apparently I should find out this coming week.
