If you read the reviews- lots of people complain about the tire chuck not working properly. When my unit came- I had the same problem on my 2014 car. I couldn't push the tire chuck down far enough onto the tire's valve stem to engage the pin valve to let air into the tire. Tried on my other two cars... didn't work on them either.
I was ready to send the unit back for a refund- when I noticed you could take the tire chuck apart, so with nothing to loose I disassembled it by simply unscrewing the clip-on piece from the threaded hose end. Inside the chuck was only one part... a 3/16" thick soft white silicone washer that was responsible for sealing the chuck to the valve stem while filling the tire. It was also the part that was preventing the chuck from fully sitting down far enough on the tire's valve stem to push open the tire's pin valve. So, I used a utility knife and shaved about 1/16" off the washer so instead of being 3/16" thick, now it was 1/8" thick. I put the modified washer (with cut side sitting against the brass chuck base not outward towards the tire valve- for better sealing), screwed the chuck back onto the threaded hose end and gave it a try out on my car.
Well, now the chuck clipped onto the valve stem very securely and instantly/correctly operated the tire's pin valve showing me the tire's pressure and allowing me to fill it to the correct pressure with just one hand.
So a two min fix with a utility knife/razor blade fixes the tire chuck problem... permanently!
As to the accuracy of the built in gauge... it exactly matched my Joe's Racing Garage (known for their accuracy) analog gauge... both showed my tires at 37PSI. I filled them up to 40 PSI and both gauges agreed once again.
If you fix the chuck, this inflator's a steal because it's all metal and good quality.. if you don't... it's worthless.
