Perfect. Works as needed. Took us a minute to figure out but we got it and it works great for airing down quickly in the snow.

Used this many times to air down quickly. Took a couple minutes to learn how it works. My friends used it and were also satisfied. I was confident with the tire pressure gauge getting down to 15 psi on steel wheels without bead locks under my TJ. The traction was better and so was the ride.

Works well. I started out as a novice with a general knowledge of how this would work. The instructions were easy to follow and using this deflator gives you a feel for when the valve cores come out. Only reason it is four stars is because deflation takes 5 minutes per tire to take out 10 psi. I use it on every trip up in to the mountains and it has definitely helped to cushion my ride on 10 ply tires. No issues whatsoever with the deflator. I would definitely buy it again as it is a must have for the trail or your "tricky bag."
