ALL-TOP Adjustable Auto-Stop Tire Deflator Valve Kit (10-30 PSI) 4 PCS Screw-on Tyre Air Down Tool for Offroad 4x4 (with 5 Valve caps)

Fast! Accurate! A few minutes a tire (35”) from 38 psi to 18 psi. Within a PSI of setting every time. Only complaint is the screw ring to lock in desired pressure is not secure enough. Screwing onto the valve stem can cause the lock ring to move and mess up your setting. You have to make sure and twist from the base in order to not accidentally move the ring that sets the pressure. Other than that, great product.

must have for off roading!! set your desired pressure, twist on and let it do its job. save you lots of time and makes it easy. definitely recommend for anyone that goes off-roading

I bought this more expensive one because all the other cheaper brands kept exploding on me this one hasn’t with daily use of 5 continuous weeks once a day, also the PSI you want goes under the bottom nut

Test each one as they're off a TINY bit. Worth the double check

This set is of good quality and at fraction of the price of the bigger brands. They are easy to adjust and dial in.

Easy to use. Really good for the price. The design is kinda cool it comes with a bag to put them in.

I’m not a fan but I will admit that it can also be attributed to user error. I switched to something else.

Works great, much faster than less costly brands. Had to dial them in slightly and, same as any other you'll find, they may let out more air than intended if you let it
