I needed to charge my wife's minivan. It has air conditioning in the rear, so it uses a lot of refrigerant. I didn't want to spend a lot of money on those large coolant canisters that come with a pressure gauge, so I bought one hoping it would work with cheap self-sealing AC canisters. This is easy and uncomplicated. It's perfect? Vicinity. It's a bit short and I'm sure the caliber isn't professionally accurate, but I don't need it. If it puts me in the "full green zone" then I'm fine with that. Too small for some applications? Possible, but not with every Subaru, Toyota or Honda product.
