These deflators work great. I’ve been using them for 3 months now. The set up is a little tedious but once you get it they are done. I dropped my tire pressure manually the first to the desired pressure. Then threaded the deflator on the valve. Then dialed the adjuster till it was right where I wanted (11 psi). Then repeated that step with the remaining three on that same tire. Then threaded them on the other three full tires as a test and they work and have been working perfectly ever since with no adjustments needed.
The big thing is to not leave them on when driving. Pressure surges from bumps, sticks, rocks, ect will cause a pressure spike and they will burp air every time that happens. So just air down, take them off, replace valve caps, put delayers away ar give them to your buddy to help speed the air down process along.

Good enough
Don't spend a penny more on the expensive grand names, you are going to get more or less the same thing. And don't expect to buy these and have a walk away solution for airing down ton15psi in a jiffy. On my 32 inch wrangler tires it takes 6 min and 30s to go from 35 to slightly under 20s when calibrated to 15 psi. It would take AT LEAST another 5 mins to go from 20 to 15 psi. The best use for these seems to be airing down to 20ish psi safely (no possibility of any one tire running away on you and loosing bead), but then it is best to just air down the last few psi with a other device. I tried drilling out the hole in one of them to 5/64 inches and that did not meaningfullly speed up their air down rate but as expected it did affect the setting slightly (see comparison image of standard and drilled deflator above). Overall a decent purchase but not a 5 star by any means.

Yes, they are not as cleanly packaged nor do they come with instructions. So far though, they work as designed.
To save you some time here’s the steps to set them up.
1 - deflate your tire to your desired PSI using a gauge
2 - screw the retaining nut and head all the way in (righty tighty) (one can assume this is 6PSI)
3 - install deflator on valve (air will come out, that’s the point don’t panic)
4 - unscrew head until air stops coming out (lefty loosy)
5 - screw the retaining nut out to hold your settings in place.
6 - re-do for all three remaining
7 - look in your recycling for some foam
8 - cut it to fit the case
9 - store the case
10 - carry on with life
I hope this helps, this is seemingly a great product. Time will tell, the lower points are because it’s not delivered as displayed. But if you frequent Amazon you know this is common. If you want things to be as displayed, then Amazon isn’t for you.

Looks like a solid product, I'm sure it will work well when I try it out.
