I have to say I had no major problems with the rigs at all. One of the connectors did have a bit of trouble getting on my nipple
but the other 2 were fine. Also on my first fill I did get a pressure drop after a bit which, like Alex says, was probably due to it becoming a bit hot during the long first fill. After the first fill I had no problems at all. The guages were a pain if you had more than one person filling 4500, but just look at your own guage on your reg and it was fine. Nice and simple.
It definately kept the queues down as you just had to push the lever and once you were full it auto dumped and away you go. If they want to reduce the flow rate then thats cool, will help with the first fill heating.
As usual a nice job by the hpac peeps.
