SAFELIFE Automatic Tire Deflator, 10-30 PSI/0.7-2 BAR Adjustable Auto-Stop Tire Deflator Kit, Screw-on Tyre Air Down Tool for Offroad 4x4 (Set of 4)

I don't leave reviews but I wanted to share my experience with these! they work great I set them to 12 psi and they dropped each tire to 11lbs so close enough, I'm glad I bought them they will come in handy up in the woods or at dunes!

I've been using deflators for years and gone back and forth with valve core removers, both the simple remover and the captured style with a gauge and then settled on the style shown here. The primary difference with the expensive brand name unit is that it doesn't have the pressure that you've chosen as a visible number. You have to fine tune them and, since I like to drop to 10 psi, remember what you set them at. To avoid having multiple sets of expensive deflators you instead set them high and then manually drop the last few pounds. It's all a pain. These are a refreshing change in that you can visibly see your setting, set it, lock it in and then be reasonably certain it will be right. Conditions change? Change the pressure setting. At the end of the day you need to be close to the right pressure, if running beadlocks it might not matter too much, but being a little higher gives you the option to go lower and maybe get out of trouble. I like that these give a good baseline with established levels of variance and nobody should be surprised when using them.

They do the job but monitor your pressure, it's not 100% accurate but it is quicker

I didn't know these existed, had always just let the air out and kept checking with a gauge. They are reasonably accurate +/- pound from my non-scientific checking.I don't do a ton of off roading but what a great little gadget for a speedy air down when on the trail. I like that they have graduations on them.I found that I can get away with using just one of the four on SxS/ATV tires. I don't run very high pressures to begin with so dropping a couple of pounds doesn't take much. By the time I install one and move to the next tire, the first was pretty much done. Now I just install one, wait, move to the next and save the up/down motions. I think Jeep or rock crawler guys would appreciate the four pack more, moving from Road Pressures to Trail Pressures would take longer with higher starting pressures and larger tires/volume of air.

Easy to use and set for fast deflation of all tires at the same time. Great look and easy to read preset pressures.
