Review on XtremepowerUS Adjustable Coupler Connector Adapter by Ricardo Tlaxcalteca

I like R134a AC adapter. They seem to be better made than many others I've looked at and have a good finish with valves clearly marked. The arrows seem to be pointing in the wrong direction, but you have to think about what they're doing, i.e. opening and closing your AC. Once you understand how they work, labels make sense and serve as good reminders. Haven't used them yet but I've tried them on the valves of one of my cars and they fit snug and well. I also love the color coded caps and brass adapters for my hoses. All in all a really good product at a reasonable price.
