ALL-TOP Adjustable Auto-Stop Tire Deflator Valve Kit (10-30 PSI) 8 PCS Screw-on Tyre Air Down Tool for Offroad 4x4(with 5 Valve caps)

What an amazing addition to my off-road gear. Exactly as described and when set properly they are accurate within 1 psi. Easy and convenient to operate. I’ve had expensive deflators and these are comparable. Would purchase again.

Amazing product, very accurate when you take your time setting them up precisely.

These are a great product! I have another set that looks identical to the Stauns, and these All-Top deflators work much better. These are consistent, but that depends on user care in consistently setting the desired pressure. These start very smoothly and shut off nicely. The lesser performing deflators had a simple flat-head valve seat, but the All-Tops use a chamfered valve seat, and I believe that is why they perform so smoothly and consistently. For my test, I set the deflation to a bit less than 20psi on the front tires and a bit less than 30psi for the rears. The fronts (both) automatically deflated to 18.5psi, and both rears went to 28.5psi. The reason for being less than the marked 20 and 30psi was that I set them just below the lines instead of exactly on the lines. The differences were trivial in terms of driving performance. One thing to be aware of is that after use, the adjustment should be backed out as much as possible without disassembling the units in order to relieve the spring compression and extend the product life.

Makes airing down 4 tires at once easier. However, they are not consistant and I have not been able to figure a way to get them to air down correctly. I have tried a test on these. Aired down 4 tires from 32 pounds to 15 pounds. Each tire was different. From 6 to 13. Filled them up and tried them again noting each tires pressure at air down. Again all different and way lower than 15 pounds. And yes, I am setting them right. I think I will buy another set from another manufacterer after doing better research based off reviews.
