Good on you for that Moley. I personally use a Hills pump, and have no problems with it whatsoever. I use an R10 and an Ultra. I can have the Ultra at 232bar from just about empty in about three minutes. Obviously it takes a lot longer to fill the R10, but I always just top it up after using it, and never have to pump for more than a couple of minutes.
Perhaps if I was buying my gear again, I would have gone for a divers bottle, but the pump works - and it never runs out!
Oh, also - Parcelforce is trackable!
