Leaked and couldn't get good pressure reading, didn't fix. Took to shop and they said my system was full of air.

1. 4 oz cans, while the “name brand” i passed up because this was 10 bucks cheaper was 8 oz cans. buyer beware2. this is as best as i can tell a “converted” 134a hose and cans: the true 1234yf standard can is a left hand thread, these are right hand. thus, you’re stuck with using their hose, and you can’t put their cans on other, better charging hoses. buyer beware.3. charging hose has basically no way to shut off the gas: use it or lose it. it’ll go in the vehicle,but if you reach the desired pressure and take it off, it is going to dump the remainder: the puncturing needle valve will not seal the can, and there is no cutoff valve. fortunately you’ve only got 4 ounces or less that you’re going to lose.Just spend the money and get the name brand refrigerant and hose set. yes, this one works as far as i can tell, but a lot of red flags here.

Had a competitors offering that my sister had purchased for a higher price. The can was unfortunately wasted due to manufacturer set up. This kit however was a breeze to use and there is sufficient left for future use

3 12 0z cans to make it look like normal 4oz in each can I could have bought 1 full 12 0z can at Napa for $70

I'd have given it five stars if there was a better seal on the needle valve. My wife's A/C was very low and 2 full cans wasn't quite enough. I had to puncture the 3rd can just to use a little bit. No matter how tight I closed the valve I could still hear the hiss of escaping refrigerant.Almost a full can bled out and went to waste.
