Works as designed to keep your a/c cooling properly. This way a the best price that I have seen for awhile. I like to keep some on hand in the garage so buying it by the case is the best way to keep some in stock.

Haven't used yet but no reason to believe it won't work. Note that these are the new self sealing cans, so the old can tap will not work and could cause the can to empty if you try using the tap made for non-self- sealing cans. Either get an adapter or a new tap before using.

Buying a/c refrigerant like this is so much less expensive than buying it by the can. We have 5 cars and they each need a refill probably once a year. The cans are sealed so the unused cans last for a long time. We've been refilling our cars for years. It isn't that hard to do. Just watch a YouTube video to learn how.

I haven't had a chance to use these yet. I bought them to restock and because the price was the lowest I could find. The manufacturer may want to consider offering one free valve per case for a year or two but the valves are fairly priced on other sites.

AC in the car not blowing as cold as it used to? No worries... this stuff is what you need to get your cool back. Pretty easy to add to the ac system. Lots of online videos can show you how and probably in the same or similar make and model. Ok 12 cans is a lot for one person. Might be nice if it can in a 6 pack but still it doesn't go bad. So just hang onto the box until next summer or when a friend's car is having an AC issue.

Brought the product just in case I need it! Product was delivered quickly, the box and product container were in great conditions. Shopped around online for the product and found Sam's has the best price per content of 12 pack/12oz cans. These are also self-seal cans. Will buy again when needed!

Great price and great product

This is just what I wanted. This is my second time ordering this product from Sam's. And they have a better price than any one else.

These cans sometime let’s u use the screw on puncture but more times than it should , it does not work .can puncture is to deep to penetrate . I think that plain sucks , for have to use the side puncture squeeze adapter . So if u do not own 1 at the time u have to run to auto store or buy on line & wait. I bought a case last year from Sams & was the wider shorter can . I even bought another top can puncture adapter to see & still no good . I would like this type can better than any if the puncture was not so deep. Do not know why a big #1 Company like Johnson could make such a mistake . Probably my last case for seems like Sams might be getting rejects or something . But price is really good so bought a case for back up since I have the other puncture side squeeze clamp kit now.

Cans have a self-sealing valve which prevent a puncture valve from working. Completley unnecessary on a 12oz can and requires additional equipment to be able to use.
