Easy to use. Fast deflation. Gauge was within 1 psi measured against Jaco digital. Fast response when checking pressure during deflation. Quality construction. Solid, quick, connection and deconnection to valve stem. Pulling valve internally and reinstalling works surprisingly well.

I'm a photographer who often finds myself driving rocky roads in the mountains. The quickest way to get through the bumps faster is by airing down my tires. I've used a variety of deflating tools over the years, but nothing that is as comprehensive or as fast as this one. I've now used it twice and feel I can confidently say it does the job faster than anything else I've used. After watching the instructional video, it was pretty straight forward. I had one valve stem that wasn't unscrewing with the tool, but JACO includes a separate valve stem tool in the package which did the job. I gave it 5/5 stars because of the speed/convince. Pressure measured the same as two digital gauges and the same as our vehicles TPMS readings. I have had analog gauges in the past that were off on calibration, but not this one. In being nit-picky, I wish the storage back was something other than black. Bright red or something that makes it easy to see and not lose. JACO banged it out of the park on this one. If for some reason it fails or I find an annoyance, I'll update this review, but for the time being, if you deflate tires for off-roading, this is as good as it gets.

Love this thing, it makes airing down so much easier. It used to take me 2-3 minutes a tire to air down from 35 psi to 20, but this thing helps cut that down to about 60 seconds to take my (new) tires from 45 psi to about 20, and the gauge is more reliable than the one that came with my compressor, so I use it as a pressure gauge when re-inflating as well. It’s a bit pricey, but if you’re gonna use it more than a couple times a year, it’s a great time saver and super easy to use!

This thing is a game changer. I’ve tried all different deflators, including the simple thread-on ones that deflate the tire, the staun/coyote ent. auto deflators, and different variations of these. These are definitely my go-to, because they are easy to use, you don’t have to keep unthreading to check the psi, and you don’t have to adjust before-hand to make sure you have the correct psi (auto deflator). The special thing about this one is the quick locking nozzle. It’s so nice not having to thread the deflator on before you actually deflate the tires. To be honest, every second counts when you’re with a group and you don’t want to be the last one ready lol The build quality is also pretty nice. You can tell these aren’t the same cookie cutter version coming from all the other brands (ARB, Rhino, All-Top, etc). I think the only thing that would be a nice add-on would be to have a digital gauge. It’s definitely not needed, but it makes it that much more convenient. If you’re comparing tire deflators, go with this one. You won’t regret it. Seriously.

This works well and is a notable improvement to my older screw on style deflators. This deflator is much faster than my older arb as it seems to have a larger release channel and the clip action makes it much faster than screwing it on the valve stem then unscrewing the valve itself. Just clip it on, unscrew valvestem, release a lot of air all at once, and reverse. I’d estimate I aired down twice as fast when using this. Gauge appears to be accurate when compared to my arb air up tool and a standard pencil gauge.

I have tried a few different deflators in the past from ones that you just screw on and stop automatically to ones like this with valve stem removals but I think this is so far my favorite. I always felt the need to double check the screw on ones to make sure they are actually deflating to the correct PSI and found they are not super reliable or consistent. And the other tools I've used didn't include a gauge making it just an extra step to remove and test the psi. This new design is really nice and quick without the need of extra steps of removing the tool to check the PSI. So far this is super convenient and accurate.

yes please. works great.
