This pump is complete bullshit. I got it because I kept it in the car so I could fill up without drama when my tires were a little low instead of pulling out my big pump that needed an extension. Unfortunately, this pump didn't work for me. I have a new car that was made in 2021 and the first thing the stock nozzle didn't fit. The rubber seal in the nozzle was too tight and actually rubbed tons of debris off the air intake threads on my car's tires. The PSI readings on the device were VERY inaccurate (the air pressure gauge in the car read 30psi and the gauge went from 38psi to 80 in a matter of seconds when I actually got it to work). Just to make sure the fitment issue wasn't just a newfangled plug on a brand new car, I pulled out my old pump and it worked just as well as it did on my old car. Maybe it'll work for inflating a weird yoga ball or something, but it won't be useful for a car.
