BUNKER INDUST Adjustable Auto-Stop Offroad Tire Air Deflator Kit, 4 PCS Tire Air Down Valve(10-30 PSI) / 1 PCS Multifunctional LED Light Features Safety Whistle and Bottle Opener/Carrying Case

Wish I would have got these sooner. I used them to air down my UTV tires at the sand dunes. It's much better putting one on and moving to the next and circling back rather than waiting at each tire with a standard tire gauge deflator.

i used the deflators on deferent cars. i adjusted them on 15 psi and on each tire i get deferent pressure after they stop. even one time all my tires got flat. i don't recommend

My first experience with these deflators was great. I started by airing down to 20 psi. They all auto started and stopped. My car had all the tires withing 1psi. The roads were rough so I decided to take the air down a little more to 17psi. This time I had to pull the plunger to get them to start, but they all stopped at 17 psi. I was very impressed with how easy the process was and how fast they aired down. The magnetic light in this kit will be great for night time field repairs.

Originally I grabbed some cheap deflators, the typical unmarked brass ones. These are much better. They are marked with PSI, so you don't have to guess and keep trying until you get it where you want it. The light is a decent little bonus. The case is the real bonus.

Bunker is making a name for themselves with recovery gear and other off road products. Their recovery boards are super cheap and yet perform really well. These Air-Down Valves pretty much fit the same description. Solid quality, good price, do what you want them to do. They are easy to adjust so that all of them are very close to the same, put them all on, by the time you get back around to the first valve, it is close to being down to the pressure you want, then you cap it off on around the rig. Well worth the price rather than guessing and going too far and having to air back up some. If you go off roading or overlanding, and you don't already have a set of these, I do recommend them. Also, I had a cheaper set and they were not nearly as beefy and didn't measure as accurately as these do. Overall, recommended.

Product received damaged

Margin of error is with in the stated range. Well made product, thick base which works perfect for those of use with fat clumsy fingers. No brainer to use. The instructions say to ling up the body with the desired air pressure... I found the true line is the locking ring and not the body. I suggest you try it yourself before using them out on the field. I added light is supper bright! I love that thing... small, easy to stow and to have handy at all times. Overall I am very happy with product

Picked up this set of offroad adjustable auto stop tire deflators, and they’ve made a huge difference during my off-road adventures. The deflators are easy to use and highly effective—just screw them onto the valve stem, and they automatically deflate the tires to the desired pressure. The adjustable settings are perfect for customizing the deflation rate depending on the terrain, giving me more control over tire pressure and traction. The build quality is solid, with durable materials that can handle rough environments. I love that they’re compact and portable, fitting easily in my gear bag, but they’re still tough enough to withstand frequent use. If you’re into off-roading and want a reliable, quick way to adjust your tire pressure, this set of deflators is a must-have for any off-road enthusiast.
