  Excellent product.

  I couldn't wait for this to arrive. When it came, I immediately opened it up and started reading the paperwork. The instructions were written for a professional, so it seems. I then Youtube'd it. A "Chris fix" video appeared. This dude explained it all in such an easy way that I was able to use the device within minutes. The value of this is easily obtained during the first usage. Cost of it with the R134a was less than a repair shop. High, very high, quality product here. I could not be any more pleased with the end result. I highly recommend this to anyone who wants to save money from a repair shop.Ver másVer menos

  Works as expected

  The gauges are good. They work as intended. I have not used the leak detector. So, no comment on that. I have not used the pump on an AC unit, but I did use it for a 5 gallon vacuum chamber to degas a silicon mold. It worked fine, although was a little under powered. Of course that is a larger volume than a car AC. I was not happy to see it spew lubricant out of the exhaust hole. I hadn't even filled it to the max line. It was a slightly below it.--- Update:Pump is still adequate. Again, not used on a car yet, but used on the vacuum chamber several times. continues to work fine. Pulls 5 Gal chamber almost to -30"Hg, and holds it there for degassing various materials. Still would like more power, as it takes a few minutes, but it does a good job. I cover the fill port with paper towels to keep from breathing in the aspirated oil. Tight enough to keep the oil contained. loose enough for air to pass. Long term, I'm going to 3D print a filter holder for it, since I use the pump frequently. Its performance makes me confident that it will work as needed if I ever have to drain a car AC system. I've used the gauges on a couple of cars now to measure and add refrigerant. Wife's AC is like new. Much better than using the single gauge cans. Still haven't used the leak detector. Every car I've used the gauges on has held pressure after topping off.Ver másVer menos

  Work perfectly. Do your learning, education for your vehicle

  never did this before but very mechanical, electrical knowledgeable. Worked like a champ, did a little studying on how and what to look for and fix my Truck AC in a couple of hours. Added oil loss and R134 to get proper readings on gauges and have not had any problems since. And is COLD....I am sure glad I did this given the heat waves that are going on. It paid for itself, it would have cost close to what I paid for it, just to have it serviced ONCE.Ver másVer menos
