DORNATA Adjustable Tire Deflator Auto-Stop (10-40 PSI) Offroad Accessories Valve Stem kit 4x4 Tyre Air Down Tool for Truck, Pickup, Motorcycle,Jeep etc. (Orange)

Just follow the instructions and it works great. High quality deflation device that is easy to calibrate and use, it saved me a lot of money. For the price, I really have nothing to complain about.

They work great! Easy to adjust and use. The pouch is nice, too. You'll love them!

The pressure readings vary from actual. But once you get them set and locked they seem to stay consistent.

This tool is really convenient for off-road driving. It saves a lot of trouble by not having to measure tire pressure manually. Its material is very strong and it still looks like new after several uses. In general, this deflation tool is very reliable and a must-have for off-road vehicle owners.

I have an unfortunate habit of putting way too much air in the tires on my car. So I bought these deflators to easily and quickly set the tires PSI to the correct level. Reading another review, they said they set them to the desired PSI an screwed onto all four tires and by the time they got to the fourth tire the first one was already done — This definitely holds true, because i tried the same thing after reading that, and it did exactly that. Very impressed by the accuracy and the quickness of these deflators. Highly recommend!
