Way easier
Definitely a must have for people who off road

3 star. Could be better made
They work but they are very easy to cross thread . With that said they do become tedious at times.

They work but not well made.
They do work and they look good, but the machining is not done well, and they're very loose. The thread tolerances are really loose and it wouldn't take any effort at all to cross thread or strip them.They also boast about having brass internals, and I don't see any brass inside.after using them a few more times, I'm dropping my review to 2 stars. They're not good, there is a variance although they're all set as close to each other as I could. There's sometimes a variance between two different deflations with the same tip. I'm not impressed.

Set and forget tire deflation
I tend to do a lot of search fishing at my local beach State Park, and that requires me driving on and airing down and airing back up. Air down process isn't hard I was using bleeders that I have to manually adjust and take off and check the pressure as needed, whereas these I can set and forget and have them be pretty much spot on each time I use them.I've used these throughout the season so far, and I can't say I have any complaints on their functionality, as they've done exactly what I needed and saved the hassle of me having the check and add air, or remove more as needed.Great metal construction, and easily put on.

Once you get them set, it’s easy
Even though the numbers are there to show the pressure, they do not match up with my pressure gauge.Super easy to use, just screw on and wait, but I recommend testing to verify they are set to the pressure you want.These are built well and I think they should last, especially if you take care of them and don’t throw them on the ground or toss loose into a tool box. Use the bag that came with them.The reason I have 3 stars is the time it took to get all 4 of them set to the same pressure (wish I had taken pictures before getting them set, because I used glue which covered up the numbers). Also, even though there is a lock washer, I recommend using a drop of glue or Loc-tite so everything stays tight.Overall, they seem like a good brand, especially for the money, and now they are set, they should last.

Not accurate
Do not recommend these. They are not even close to being accurate. I set them for 20psi and they kept letting air out until I stopped it. It went down to 12 lbs.. 1 tire stopped at 25, another at 17… does not do what the more expensive brands do!

Very Accurate between 10 - 20 PSI - a little tricky to set up
I know some people run their beadlock tires down at 5 PSI or lower, but these only go down to 10 PSI, and even that is a little tricky to set.Basically, you will loosen the small lock nut closest to the main body ("deflator shell") that screws onto the valve, unscrew the center shaft (deflator pin with spring) with the red plunger / piston, and start looking for the pressure number you have in mind (either BAR on one side or PSI on the other). Line up the setting you want on the top edge of the body and then tighten the lock nut down. At this point, when you screw the device onto the valve of your tire it should start hissing - letting out air until it reaches the desired pressure.I tested these on my land cruiser. I found one of them struggled to air down to 25 or less PSI, but I wouldn't normally air down if I was only going that low. All four were able to hit within 1 PSI of 20, 15, and 10 PSI.My only real ding on these is there is a taper to the threads on the "piston" side, so it starts to wobble in the hole as you approach the lower PSI settings. I found it worked well as long as I tried to keep everything lined up and straight as I tightened down the lock ring, but it does take a little focus and attention to do that. Additionally, if you loosen the piston side all the way and then try to screw it back together, be very careful to keep things from misaligning and cross threading.Item Reviewed:X-BULL Automatic Tire Deflator,Adjustable Offroad Accessries,4pcs Auto-Stop Tyre Air Down Tool Kit for 4 * 4 Vehicles,Truck,Jeep with Storage BagX-BULL Automatic Tire Deflator,Adjustable Offroad Accessries,4pcs Auto-Stop Tyre Air Down Tool Kit for 4 * 4 Vehicles,Truck,Jeep with Storage Bag

Great Value for the Money
This is a great quality set and comes in quite handy when you need to deflate your tires so they don't pop.
