12 Brass Adjustable Automatic TIRE DEFLATORS 4×4 Offroad with Instructions and Colored CASE

These work well enough. I followed the instructions on how to set them and just came to realize that I'm going to need to keep adjusting them and testing to get them at the correct setting. I set them all to drop pressures in my 4Runner to 18. They ended up ranging anywhere from 16 to 20, so I'll have to just keep playing with them. Otherwise, they're great. I can't imagine any others would be much better.

Not the easiest to set but doable. Love the price and quality!

Works great. Once calibrated, it bled out the air consistently. Saves a lot of time.

They work wonderful, no issues. Slight learning curve to set up, but very minor.

They work great for my Car driven in UAE desserts !

Set Inconsistent

Fast delivery. Just as described. Would be better with individual pouches like the picture which it all came in one bag instead.

They saved me a lot of time when I got to the beach to air down 12 tires.
