Great price no issues works good

It seems to work just fine. Had no idea how much oil was already in it and so had to drain it out. Seems to be 1 Ounce of oil already in it. I replaced everything except for the Evap inside the truck. I replace the Compressor, Condensor, Air Accumulator, and even the Orifice Tube. I flushed everything that was left with AC Flush. The system required something like 9 ounces of PAG 46 Oil, Which was 8 ounces. Plus the 1 in the compressor equals 9 ounces. There was no oil left anywhere else as I replaced or flushed the parts. I dumped in the 8 ounces of oil into the Air Accumulator before I installed it. That was the easiest way to do it. The compressor won't run until there's enough 134a in the system as you start filling it up and it'll cycle on/off briefly and get longer on then off as time goes on as you add more and more 134a until it's on non-stop. This allows it to get the oil throughout the system without damaging the compressor. Before long most, all of the oil dumped into the Air Accumulator will be gone. It's spread evenly throughout your system. Before you open your system up, make sure you have the 134a already in your system pumped out. I cost me about $35 to take it someplace that does AC work to do that for me. Make sure you use a Vacuum Pump on your system for about an Hour, when done, let it sit for 30 minutes to see if there's a leak. It was getting late and cold for me up to that point. I disconnected the Vacuum pump. Put the gages into the Engine compartment and closed the hood to come back the next morning. When I checked the gauges, all good, still under a vacuum where it was the night before!!! Clearly no leaks after hours. The system took close to 3 12 ounce cans of 134a. Not quite, I think it was 32-34 ounces and 3 can is 36. I didn't quite use all of the 3rd can. I went and added what was left to an old jeep, which I fixed many, many years ago and figured it was low. It wasn't reading low, but I added what was left in the car into that system just to finish off the can.
