John Yoder: Love the quality of these deflators! Once adjusted to your specs, they'll be spot on every time you use them. Great time saver for airing down for off highway exploration!

Amazonian: I had nothing to compare these to but I had heard from another off-road friend that this type of product existed so I searched and decided on these. they are simple to use once you understand how they work. They are pretty accurate. After calibrating 1 of them to my desired tire pressure I just used that one and rotated it on to all 4 tires which made them all the same pressure. You also can calibrate all 4 of them and then use them all simultaneously. OR.. if you want a set of them calibrated at different pressures you can find some way to mark each one and then choose which tire pressure you want, then move that 1 cap to each tire. Anyway.. not trying to confuse anyone.. these really do work as advertised and come in a nice little pouch to keep them together. They also came with a tire gauge but I didn't use that.

RuNuts: I purchased a set in January and one of the deflators was not working properly. It would not stop the deflation allowing one of my tires to deflate too much (Almost flat). I contacted the company and they were fantastic to work with.

A replacement was provided and the setup was painless, quick and they work great!!! I’m dropping 35x12.5x15 from 35 to around 18 Psi with no issues.

Pros:
Easy to set - up to the proper pressure - follow the directions exactly and don’t try to be smarter than the manufacturer
Quick to use
Good case
Seem to be great quality

Cons:
With the replacement - no issues
The bad valve was problematic out of the box but made right by great customer service
The included pressure gauge - it’s a joke - if you are buying tire deflators then you already have a quality gauge and air up equipment on board

Andrew Bryan: I will start with saying I have never used the higher end versions of this and these were my first try at using an automatic deflator. I pre set all 4 at home before going out to drive on the beach to 18 psi and setting them to your desired pressure is extremely simple and easy to do. The bodies of them seem well built and the spring feels substantial enough to last. When I used them they did worked properly and let the air out but I did have to monitor them as the tires got lower. One stopped about 10 pounds over the pre set pressure and I had to pull the stem of the deflator to make it keep going. Another went 3 pounds under the pre set pressure and the other 2 stopped with in a pound or so. Over all I am happy with them but would advise to definitely keep an eye on them but for me to have and use 3-4 times a year I am perfectly happy with them and it beats kneeling by 4 tires for 30 minutes.
