Literally opened the packaging and quickly found that one of the hose connections was missing a thread. Yes, there really wasn't a thread. There is a female connector to connect the hose to either an automatic quick disconnect or a refrigerant bottle and there were no threads. It looks like the manufacturing process missed that connection. I had to use a tap to create the thread myself in order for this thing to work. I'm also not 100% sure the high pressure gauge is accurate.
