Pro-C A/C Professional Digital Display Automotive Recharge Gauge & Hose for R-134A Refrigerant, ACP400AD

My AC pro gauge I suspected was bad and I hooked this gauge up to the cab which was 5 years old and it reas accurately and I was able to get cold air again in my card! Easy to read and use! Saved me hundreds of dollars or thousands that a shop would have charged me

This was the best purchase. Now I can purchase refills and save $150 or more that the mechanic charges. So easy to use and YouTube, well, enough said.

Worked well and is easy to use. made the job go quickly with the easy read display.

Very easy instructions and boosted my AC immediately in my 15 year old car.

For the price, this recharger was a great value! I needed to quickly recharge the a/c in my wife's car and it worked extremely quickly. The product comes with great instructions to follow and the connection stayed secure throughout. I've used the product three times since I purchased it and the third time I used it, there was some leakage. It wasn't anything major however it was noticeable. It didn't affect the recharging process at all, as far as I could tell at least. Overall, I'd recommend this product!

Muy buena herramienta, excelente calidad y fácil manejo, no puedo determinar su precisión pero por lo demás muy buen.

Two main flaws with the one that I received. First off, and most importantly, the quick connect did not seal around the A/C service port. That was noticed right away, after connecting it to see how much pressure the system had. Loved the digital display, and I have every reason to believe that it was accurate. Next, piercing the can with the finger lever was nearly impossible. It just didn't extend far enough, really. After a few attempts of removing the can and reattaching it, tighter each time, it finally pierced it. I was afraid I was tightening the can to the gauge to the point that the plastic gauge was going to break. Everything seemed good at that point, other than the small leak at the service port. The one can I used with this was essentially wasted as it boiled off/evaporated somewhere between the connection to the gauge and the service port. The pressure in the system was actually 7 psi lower after attempting to charge it with one can. Afterwards I used my old charging hose, and separate gauge, to add a can to the A/C system. I was hopeful that this new unit would save me the inconvenience of of switching between my charging hose and my gauge to see how much I've added to the system. There are other charging hose and analog gauge sets out there for the same price that have less plastic parts than this unit, and will likely do the job without leaking.

This product worked well. The only reason I purchased it was because it has been a long time since I had to charge an A/C system on one of my vehicles and I was afraid that the old hose assembly I had wouldn’t work with the new style of self sealing can. Turns out, it says on the package it will work on self sealing cans and on the older style of cans that require a puncture to open. Had I known that,(not stated in the product description) I would have just used my old analog gauge hose assembly and saved 20 bucks. Not sure how long the battery is going to last in storage since I can’t take it out or replace it without damaging the device. Next time I need it, it probably won’t work because the battery died.
