Worked as intended on my 2010 328i. Turns out I did not need that much to get my a/c as cold as it used to be. I saw a review talking about how the bottle itself is cheap, why focus on the bottle and not on what it does RIGHT. This product works just as good as any other brand. And for cheaper!

The bad reviews here are ridiculous. I am not a mechanic, but I have the internet and some basic sense, and was able to figure it out. I used this in an F-250 7.3 diesel, and found that the can instructions were more than adequate once I located the correct port to plug into. Make sure your system is on, otherwise the gauge will show that the cooling system is overcharged…the can tells you all of this. Again, the other reviews noting that the refrigerant doesn’t flow clearly didn’t follow the (fairly straightforward) instructions on the can. If for whatever reason you find that the instructions on the can are confusing, the internet is a remarkable place (that we’ve had at our fingertips for a good number of years now). There are countless videos available to watch, including step by step, specific instructions for whatever vehicle you’re looking to recharge. For the bad reviews stating that it doesn’t work for certain vehicles…maybe google compatibility before spending almost $40 on a can of refrigerant?

First and foremost, make sure you wear eye protection and gloves when using this product! This is not stuff you want to avoid safety on! As far as the product goes, this stuff is kinda meh. It will (mostly) get the job done, but it's a bit of a pain. The hose is pretty short, and I'm not sure that I fully trust the gauge. It caused a bunch of existing freon to shoot out of the valve when connecting it. When I turned the can, the connections kept loosening, so it leaked from the can. Enough leaking that one bottle didn't finish my car. Next time I'll likely spend a few more bucks and buy a different brand

Don't bother. The valve connecting to the low pressure port had a bad seal. Most of the refrigerant sprayed into the engine compartment. The gauge seemed to register pressure, then completely drop. It seemed poorly made, with cheap plastic, so I'm sure this wasn't a one-off. Save your money and ask for a recommendation at an auto parts store.

Don’t buy this product complete waste of money and time

It does not work for Honda Civic
