Rhino USA Adjustable Tire Deflator Kit (10-30 PSI) Ultimate Screw-on Automatic Tire Deflators for Offroad - Quick & Easy Air Down System for The Trails - Best Jeep Off Road Accessories (4-Pack)

Excelentes!

These work amazing use them on my truck to air down but I also used them to air down sandrailThey are accurate and amazing

I purchased these especially for a local Jeepfest I was attending bc I knew we would be driving on the beach & would need to air down. That can take time going tire by tire, so these are perfect for that making it a quick process. They are very easy to set, so your tire pressure is the same across your tires. They seem to be very durable. They do come with a little keychain pouch to keep them in so they aren't just rolling around in the glove box or you vehicle. I think they are a great value for the cost & would totally recommend to anyone that likes to offroad or drive on the beach, etc.

Works like it's supposed to .

Set these to 20 psi, ended at 8.Set them at 15, one ended at 5 and one ended at 19.Super unreliable, wish I could get my money back.

I use a trailer tire to set these. It would take too long to set them on my 40" Jeep tires. I set them at 15 psi and that is what I got. Right on the money! All four of them were pretty close.
