InterDynamics Car Air Conditiioner Gauge and Hose by InterDynamics, A/C Pro Air Conditioner Recharge Gauge and Dispenser for Cars, Trucks, 24 In Hose

When I first attached it to the low-service port the reading was in the red zone which scared the crap out of me. Then I realized from the instructions that I forgot to turn the AC on. The reading then dropped to 17, which indicated the refrigerant was low. Followed the instructions and got the reading up to 30, which is in the filled zone, and her A/C is working fine now. However, there could be a leak, and only time will tell. But for now, everything works great, and I would highly recommend purchasing.

Great product. Satisfied Customer.

Works fine and does all I need to top off the freon in my older van. This is my second one and the first one only lasted about a year before leaking so hopefully this one will last longer. Dropped one star for how long it lasted.

Es muy muy bueno trabajo excelente lo recomiendo congela muy frío

Easy to use and quite effective.

Well got the digital gauge by mistake from Amazon so thumbs down for Amazon. I ordered the non-digital gauge because of my doubt over longevity of digital and reliance on battery... but I needed to fix AC ASAP since it was extremely hot and muggy out, July in New England!... so despite my reluctance I decided to try it. Used it 2 times for a total of about 10 mins... turned it off when stored and made sure battery was not being accidentally turned on and it's dead now. Called InterDynamics and explained the problem and they said they have no warranty for their gauges and that it's likely a battery issue... so I have to take pics of the battery and submit it to energizer for a "Possible" new battery, and I have no idea how long that will take even if I do get a replacement battery. I need it now since my AC still needs tweaking to operate it optimally during the worst months of the year. I told them that if the battery was new, indicated by the fact that I had to pull out the plastic tab that kept the battery from being drained during storage and shipment that the battery was probably not the issue, but they don't see it that way. Even after I told them I had pretty varying pressure readings from first reading to second reading... and I know it can vary but still makes me wonder. I wanted them to replace it with the non-digital version but I got nowhere with that. Last A/C Pro product I'll buy... they are overpriced anyway and I only bought this one since I just happened to find it discounted on Amazon that day.

Made super well. Easy to use. Better than the rubber and plastic ones. Great price

Great product
