The Staun Automatic Tire Deflators are a fantastic part of our off-road kit! I screw the first one on, and air begins to gush out of the tire. I move from tire to tire, screwing a deflator on each tire as I go, and by the time I get back to the first tire, it is finished! Then, by the time I finish unscrewing that deflator, the second one is finished, and so on. It is seamless and very quick. They come with a small, sturdy soft carrying case with a snap closure. They also came with excellent instructions for setting the automatic pressure level. They are advertised as being calibrated to 18 PSI from the factory, and our set was dead on at 18 PSI for all 4 deflators. Changing the pressure setting is a simple process that takes just a couple of minutes. Just set the pressure in your tire to your desired PSI, screw the Staun deflator on, and adjust the top of the deflator by screwing it up or down until the air flow out of the tire stops. Next time you use them, they will automatically stop airing down at the desired level with no intervention. Easy!Unlike many automatic deflators, the Stauns allow air to continue to flow out at full pressure right up to the moment they are finished, and then they shut off with an audible noise. They are not pressure dependent, slowing down as the air pressure reduces, so they are extremely quick. We love these auto deflators! They were expensive, but absolutely worth every penny! 5 Stars.

These work perfectly! I wanted them set for 20 PSI and it took me about 5 minutes to adjust them from their factory setting. I've used them four times now and every time they deflate my tires to exactly 20 PSI per my gauge. They are a little pricey but I feel that they are a good value because they are reliable and have worked perfect every time I've used them. I have 33 in tires on 8-in wide 16-in rims. I put the first one on, and then go around to the other three tires and put them on. Wait about one more minute or so and the first tire is done. By the time I take this off and put the cap back on the valve stem the next tire is done and so on. I love the fact that I can just screw them on walk away do some other things check my trail gear, check my winch etc and don't have to keep going back and check the pressures. If you want something that's simple and easy and is a set and forget item, these are what you've been looking for.UPDATE 9/20/19Now I have used these 26 times. I keep a log when I go four wheeling so I know where I was and make notes of how the trail conditions are and so forth. so it's easy for me to see how many times I've let down my tires. I changed the setting to 15 PSI as I got new tires that have much better sidewalls and allow me to air down further. They're still working flawlessly every single time. Highly recommended product for sure or any four-wheeler. I also bought another set for use with my dual sport motorcycle. I only need two of them for the motorcycle, but this way I've got a couple spares in case I lose one or eventually any of them we're out.

I used these for the first time last weekend to air down and I found the following:Pros:-These are very easy to use, screw on to the valve stem and let it go until it stops-They are solid brass-Worked perfectly as intended and don't seem to "taper off" as bad as the cheap ones-They air down fast (faster than the fellow jeepers doing it manually or with a valve core kit)-First one was finished by the time I installed the last one on the opposite side-Comes with leather pouch to store with the other gearMinor Cons:-No markings for on the fly adjustments (Some markings for round numbers would be nice for on the fly adjustments)-According to the slow on board TPMS, the tires were 16-17 psi when finished (tires were warm when deflating though)Overall these are solid deflators, easy to use, and seemingly easy to adjust so I can get them dialed in. 18 psi from factory seems like a little too much for me and we lost some clearance on the trail, some markings on the deflator to show round numbers ie (30, 25, 20, etc...) would be great to get a general idea when you misplace your tire gauge when off-road.

Work accurately and fast, they came set to ~18 PSI. By the time I come back around to the first tire it's usually finished.

I can never seem to get these to deflate the tires evenly. They stop at +or- 3 psi but never exactly where I want. So, they are ok, but not perfect.

Easy to set to desired PSI with a good range from low to high, easy to use. Case is handy to keep all four deflators together and quality is excellent. We were with a friend who purchased cheap knock off brand and he ended up using our deflators. You get what you pay for😃

I used these for the first time 4x4ing in Death Valley Thanksgiving weekend. The deflators dropped the tires quickly and very all close to 18 PSI as promised. Solid material. Look to last. Happy I purchased 2 pair while on sale. I have one set for 18 PSI (factory setting) and other at 25 PSI for quick drop when driving well maintained fire roads.

Tested these bad boys out in my driveway before a trip. Relatively flat, level ground. 285/70/17 Nitto Ridge Grapplers.Airing down took about 2 minutes from screwing on the first one until they all stopped hissing. Checked all 4 and PSI ranged from 17-19, with the advertised factory setting at 18 - so pretty much spot-on, especially for off roading standards. (1 PSI either way really doesn't matter unless you're running them super low, and if you're that low, you probably have bead locks anyway...)I'm happy with them. Solid brass construction, will definitely last a long time. The variance in the tire pressure at the factory setting tells me that they're calibrated by hand and inspected. I think the carrying pouch will eventually pop a stitch or two, but you'll probably lose it on a trail before that happens.

Got those when my rugged ridge rip off got stolen by an idiot. They deflate very fast until the desired pressure (14PSI for me) and all 4 tires at the time. They are also quite easy to adjust. Screw them, prepare other stuff or talk with others. come back and it's done. They don't slow down when they approach the desired pressure like the cheap ones. They close with a snap at the right PSI.

These worked better than expected, worth the price. Good quality.

Work exactly as they should! My running pressure for my Goodyear Duratracs is 32psi, these deflators take me down to 18psi (the preset) in not much longer than it takes to walk around the truck and put them on. Great way to save time and hassle when airing down!

Amazing deflator. Just screw it in and talk to you friends while your tires deflate by themselves. YES it is slower than other type of deflators. But this is Way Easy. Just set them to the right PSI and Go off roading !
