Hmmm, I'm not convinced, some of the claims seem a bit much to swallow. Never tried it and probably never will but I'd be interested to hear hands on reports

These guys just try to make money. It is difficult to save 20-30%. Show me the numbers. This is an "advanced" type of liquid receiver. They claimed that this receiver can be used for a/c, refrigeration, compressed air. No liquid air in compressed air systems.???
