ALL-TOP 4x4 Digital Tire Deflator kit/Air Down Master/Rapid Tire Deflator/Professional Tire Pressure Gauge (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.

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.

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!

Air doesn't come out any faster than if you hold something to the valve
