I got the same reply from picturebrite almost half a week after I ordered a cylinder from them.
I bought a hose and a connector from them at the same time and after much aggravation they have refunded only the cylinder cost.
I ordered everything almost a week ago and am still trying to get them to give me my money back for the hose since a hose is completely useless without a cylinder. If I don’t get my money back I am starting another thread to warn others about this shitty company.
