Good quality but they take a long time to reach the low end of the pressure you set them at. I just set them to a pressure lowers than intended and when air escaping slows way down I test the pressure. It is usually only 1-2 lbs off of my desired pressure.

Convenient and well made!

These were incredible. It took maybe 10-15 minutes to get all 4 set to the deflation level I wanted, after that I just twisted them on and each time they stop letting air out on the exact lb I want. For the price these were and the job they do? I would buy again in a heartbeat. Also, they come with a small carrying bag which is great.

If you off road and air down your tire you need a good set of Deflators

Purchased these back in 2014 when I got my Xterra. Set them up as directed and stashed them away. This month, while towing a small travel trailer I got stuck in the sand. Dug the deflators out, put one on each tire, and in about 10 minutes the hissing stopped. Used a shovel to remove some of the sand behind each wheel, put it in low range and both SUV & trailer came out without a problem.I also purchased a Viair 00088 88P Portable Air Compressor and it worked great to reinflate the tires. I did let the compressor cool between each tire before doing the next tire.

Great stuff. Did the work.

This is a time saver. Get to the trails much faster.

Work as expected
