I live in Tennessee andthe weather changes and I try to keep my tires properly inflated for Performance and longevity. I also race a car at the track requiring constant monitoring of the pressure in my rear tires primarily. This device works easily. There is somewhat of a learning curve, but once you get it, it’s easy to.

Awesome product. Great build quality, easy and satisfying to use (once you read the instructions), and deflates SUPER quickly! I use it to air down my ‘97 Land Cruiser. No complaints.

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.

I was recommended this product by a friend of mine and I was not disappointed. I've been used Jaco's quick deflator for the past few trails and I'm extremely impressed. Build quality is very good and the design is simple. It deflates much fast then all the other styles of tire deflatoras that I've tried and is simple to use. The quick connect and disconnect on to the valve stem is extremely convenient. While my brother has to screw his on , my Jaco just clicks on, holds the seal and deflates quickly. If you find yourself deflating your tires then this is a must have tool.

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!

I'm a big fan of this tool! The quick connect saves time unscrewing and prevents cross threading on the valve stem. The gauge is accurate and well cased so it will hopefully stay that way. The core remover and air release mechanisms are made of trustworthy metal that function exactly as described, no fiddling needed, no leaking. Even the packaging and enclosed instructions were well thought out and speak further to the quality and care that Jaco puts into their products.This tire deflator is an excellent tool for a great price. I recommend it
