2 in 1 Professional Rapid Air Down Tire Deflator Pressure Gauge 75Psi，Rapid Air Down Offroad Kit with Special Chuck for 4X4 Large Offroad Tires on Jeep, Truck, ATV

This guy works well to get your tire pressure down in a hurry. Its actually removing the valve core to deflate the tire, then reinstalling it once you get the desired pressure.It does a nice job, but I can see where an old, corroded valve core could make a mess of simply airing your tires down.

The box comes in handy and is convenient to keep in the trunk of my car. In the box, there are several smaller pieces I didn't use, but it's good to have them for the future. Overall, it was very easy to use on my car tire (removed the cap, pushed in, done), even though it's my first time using a deflator.

Having four deflators makes air down of 35” Wrangler tires to below 20 PSI in 10-15 minutes. Use Jeep tire monitor as they deflate so it is easy. No need to remove cores. Pressure gauge allows check when system is off and fine tune deflation or inflation.

A little tuff to screw on and off and may be a psi or two off but over all works great

One out of the 4 deflators does not work. Just keeps leaking air. I was able to calibrate the other 3. The guage seems fairly accurate within 1-2 psiUpdate, reached out to seller and they have taken care of problem. Great customer service.

The gauge doesn’t have markings or numbers so you’ll have to guess/measure the pressure the first time. As long as you don’t twist it again you should be good to go subsequently. It’s so much faster than traditional tools. Screw it on and fuhgettaboutit.

There is nothing to dislike of this product, all the features work as aspected

Works just as good as all the over priced ones but if you loose it you hate your self less so thats a good thing
