Good product.
Amazing Product, but it depends on:-
1. What you are going to use it for. (refilling your air conditioning from empty, or just topping up).
2.What type of car you have.
3. What pressure you air con works at.
I found (on my 1.6 Petrol) 2007 Citroen Szara Picasso) it will get you air con going if it is completely empty. (assuming that you have no leaks on your system of course!).
However, I found (on my Picasso) that for topping up the system (one you have initially used a can to pressurise the system and get it working) the cans do not have enough pressure in them to top the system up to keep it working.
I found that once the pressure in the system reaches the pressure remaining in the top up can of gas, no more gas will go into your car's system - the pressure seems to equalise between the car's air con system, and the pressure remaining in the top up can.
Consequently, you end up wasting perhaps 1/3rd of the can, and have to purchase another full can to enable you continue topping up the car's system. The same thing happens again when the can's pressure equalises with that of the car's air con system.
I ended up taking my car to a garage and paying £70 to get the air con system topped up. It has worked perfectly since then. (the garage found only 400grms of gas in the system, and they put in 700grms!)
They told me that the DIY cans of gas are OK for smaller cars where there is less grams of gas in their systems, but are no good for larger cars.
That's about all I can say really.
