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

Used these straight after I received them and found them very easy to set the correct pressure for deflating. The TMS system indicated the exact pressure that I set them at along with the tyre gauge when I went to reinstate. Great product, accurate and appear to be good quality

Really nice helps in efficiency and accuracy of psi and time consuming

Does the job well but is not accurate enough. If you don't check it might not close and deflate to the set pressure. You should always keep in mind + or - 2 psi.

Better than all the other products!

Pure waste of money! Does not work properly even after setting them accurately as per instructions. Error is very large. They will even completely deflate the tire.

Works well

Setting at lesser PSI is bit tricky but does the job

安価な商品なので正確な空気圧の設定は出来ませんでした。 何度か試してみて希望の空気圧手前で大凡で設定、その後はエアゲージなどで手動で空気圧を合わせるなどすれば便利に使えます。 私はオフロード走行時に毎回使用してます。

The ALL‑TOP Adjustable Auto‑Stop Tire Deflator Valve Kit exceeded my expectations. They were very easy to adjust, and the first time I used them, they hit my target PSI within one pound. That kind of accuracy right out of the box is impressive. They also come with a storage pouch and metal valve stem caps, which are nice bonuses that keep everything organized and ready to go. The build quality feels solid, and the auto‑stop feature works exactly as advertised. I was so impressed with how well they performed on my truck that I bought a second set for my son’s truck. If you want fast, reliable, and hassle‑free tire deflation, this kit delivers.

Good quality. I like em.

A cost effective solution that takes most of the guess work out of airing down. Well built product that does what is intended to do and if not mistreated, will last long. They are not 100% accurate; may be off by 1-3 psi or so but just need to do your own “mini calibration” on the first go around and you’ll be happy.

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.
