5.0 Works great.

Works great. Setup can be simplified by using a bicycle tire to get them all set to the target pressure. Take your time with the fine tuning and you'll be more than happy. Came in a nice storage bag. I have ran some of the other similar deflators and they all work the same to me. you will notice different shut off pressures if you are driving, but you shouldn't be driving when these are on the tires. I have mine set to 10 psi. on a 35x12.50R15 they deflate a little over 5 min. Use that time to disconnect sway bar.

4.0 Work well, easy to use

Deflators are compact, easy to set end pressure, although there aren't any graduations or reference marks on them. I did observe that after setting them to 25 PSI using my Jeep's spare tire (30X10.5R15), when using them on my Frontier's tires they deflated to under 20 PSI.

4.0 Simplify Life

The time spent off-road is limited. Anything that can increase the time you have for fun is a good thing. Being able do air down all four tires at the same time and to the same psi simply gives me more time off-roading. These deflaters are fast, are made of quality brass, and are adjustable to the pressure I want. I am on the back roads faster, meaning I am having more fun sooner. I love them.

Air down for off road use. One was defective when received, was replaced rapidly. Easy to set.

5.0 Removal of air from tires. Check!

They take some initial set up but it's quite clear that the added traction from airing down is beneficial. What can I say about them? They let the air out of the tires. The last time I used them it was pouring rain and I was nice and dry inside the jeep while my buddies were outside with a tire gauge deflating one at a time. One finally gave up and I let him use these things. Since then he bought a set.

5.0 Quick and Easy

Set the PSI in your spare tire to the level you want (I set mine at 15 PSI),put the deflators on one at a time,turn the ring to set it and you're done. Don't forget to reinflate your spare to a higher PSI ( if that's where you keep it) when you're done. You can deflate all four tires at once in a matter of minutes. Works great.
