Adjustable Auto-Stop Offroad Tire Air Deflator Kit, 4 PCS Tire Air Down Valve(10-30 PSI) / 1 PCS Multifunctional LED Light Features Safety Whistle and Bottle Opener/Carrying Case

As described

Very easy to use. As precise as my tire gauge is.

These simply don't work. For one, they never stop letting air out. They just completely deflate the tire every time. For another the range isn't 10-30, the set screw bottoms out in the housing around 24 psi. So if you need higher than that you're out of luck. I'm returning them.

Originally I grabbed some cheap deflators, the typical unmarked brass ones. These are much better. They are marked with PSI, so you don't have to guess and keep trying until you get it where you want it. The light is a decent little bonus. The case is the real bonus.

Excellent product. Require some adjusting for whatever psi you’re looking for. I would also trust your ear, sometimes they don’t auto shut off right when they are supposed to and will take the psi lower than intended. Overall 9.5/10 would recommend.

Was threading good for first set pressure of 20psi. The next day I reconsidered and was going to change the psi to 30. However, would not thread past the section of the retaining nut of 25psi. I haven’t actually even used them yet. All 4 of them will not thread to 30 now. Keep in mind, I use alot of Bunker Industries products from the tire inflators to traction boards.

These work great and are super easy to set

Wish I would have got these sooner. I used them to air down my UTV tires at the sand dunes. It's much better putting one on and moving to the next and circling back rather than waiting at each tire with a standard tire gauge deflator.
