4 Way Tire Inflation Deflation System with 4 Closed Flow Air Chuck Digital Tire Pressure Gauge for Car Trucks Off Road Vehicles-Compatible with HPA Tanks and Compressors

Great deal. Works as intended. Airdown function is very slow indeed , but I haveAutomatic deflator kit for that purpose so it doesn't bother me.

Great build. Quality parts. Accurate gauge. Extremely easy to use. No leaks.

It get's the job done and saves my back from bending and stooping more than I need to. If you want speed down and up then buy something else. This will do all 4 tires at once, air down from 27 to 15 lbs. took 6 minutes. Air up from 15 to 35 took a little over 11 using the Maddox single cylinder compressor. There is an adapter from the Japanese fittings to the imperial ones by Thor's Lightening I believe on here for sale. It will help in the air up as you won't be going through a valve stem.

Works just fine, easy airing down or up.

Works as well as the more expensive units. I demo on YouTube Grub and Gravel

I was very surprised at the quality of the product after using it several times I’ve had no issues at all well worth the money. I use it for airing up my 40s on my Jeep gladiator.

Seems well constructed, but I find the hoses to be stiff and thus difficult to roll well and store.

It was leaking air from the second use and thought maybe it was loose parts. But turned out to be a cracked nozzle head. The metal is really soft and cheap !
