My a/c needed recharged, husband was gone, so he walked me through it. Was able to use 2 cans and now it works great. He tried to recharge it with another much more expensive brand with no success. Easy to do especially since I've never done it before. Great price.

R1234yf cans are supposed to be reverse thread, but these are regular right hand thread. My hose with a pressure gauge wouldn't work on them because it is LH, so I had to use the hose that came with the cans.Each can is only 4oz

I bought these for my car as a trial to see if the dye actually works I had a condenser leak and I have a video of a visual leak and I put in two cans of die and nothing showed a leak we had to use the old school style of soap and water to show the visible leak this is a fraudulent product do not purchase. Try this on two of my vehicles where I already knew where the leak was coming from just to see if this product works or notUpdate: I had an issue with my first order as seen above and had originally given it a bad rating but when I messes the seller within three days everything was resolved and the customer service was just excellent and very responsive would do business with them again :)
