ALL-TOP 4x4 Digital Tire Deflator kit, Professional Tire Pressure Gauge, Air Down Master, Rapid Tire Deflator (250 PSI)

Not exactly sure what the problem was with this deflator but I only used it about 6 times before I started having issues. I connected it correctly but basically, no air would be let out of the tires. I borrowed a deflator made by another company, yes it was more expensive but it was made better, including thicker and better quality connections and hoses. Do not waste your money. Cheaply made and unreliable.

Super certero. No tengo que descenroscarlo para saber cuantas psi tiene.

To figure it out. But once you do it works very well. Deflates fast. Overall quality good. The reading gage turns off too soon in my opinion. I would recommend but takes a bit of practices to get it to work correctly.

There are many different design and types of air down tools. I have try few, and this one by far is the best and fastest tool I had use so far. for smaller tires 30 inch or under may not be big different. but when you air down these 35 or 37 or larger tires. this tool make a big different. Love it!

So this device works to a point. They have a super small o-ring deep in the barrel that is supposed to seal something on the stem somehow. What happened is that by threading on and off a few times, the o-ring ground up into debris that plugged the valve core. Lucky I'm technical and was able to dig it out. The gage shuts off quick. Plus side is that the batteries extend. Minus is that every time it is disconnected and reconnected it needs to be turned on again. Outside of that, we shall see how long the o-rings last inside of this device. It's pretty cool in what it does and how it does it as well as it has the ability to unthread the valve core too.

So far, I’ve only tested it on one tire at home and it works as described. I’m only giving it three stars because it was a little difficult compared to other deflators I’ve used you have to play around with it a bit to get air to start releasing at the proper rate. The pressure reading was fairly accurate compared to the onboard tire pressure gauge. Edit: I’m editing this review after taking it out on a couple trips, my advice is spend a bit more money on a better brand. Even though it looks exactly like the others, but it actually does not perform like the others. I constantly have to play with the valve to get air to release. It’s very aggravating. It will release air slowly then stop. In this case, you’re definitely get what you pay for.

Simple to use

Very high-quality and easy to use
