Overall this was a good kit at a great price but the canister connection was flimsy resulting in the second can being stuck onto the triggervalve assembly trigger valve assembly and canister twisting around together

I had to disassemble and bustoff the lower portion of the plastic housing in order to get to the brass fitting to unscrew the canister

Then i had to reassemble the housing and carefully screw on the third canister to use the remaining refrigerant

Thats when i saw that this product is meant as a recharge not a new charge

I was only able to add in perhaps 34 of the second can and the system was showing to be properly charged for the temperature at the time and the system was blowing cold air again

You have to release any existing r12 out of your system before you add the new 134 refrigerant

The thing will only fit the correct valve so you cant really mess that up

Short money to spend to find out if your ac will work or not
