Digital Tire Pressure Gauge 300 PSI with Stainless Steel Tyre Chuck - Rubber Case Large Dial with Deflator ANSI Tested - for Car Van Truck Aircraft Tires - Made in Taiwan

Just received the tire pressure gauge and was impressed by the quality and dual swivel ability of the hose. Checked the pressure reading to my other gauges, both digital and manual, and found them to be within +/- 1, except for one digital item that I was not comfortable with and prompted this purchase. The swivel makes use much easier when checking duals on my motor home and then switching to my truck and tractor. Time will tell regarding longevity.

First use everything went well. Easy to read, measuring 250#. Second use all zeros. Changed batteries, all zeros. Returned, no hassles.

No instructions came for installing batteries. Took me a few minutes to puzzle out how to remove the heavy rubber casing to gain access to the battery compartment.Reads lower than my other three gauges, which range from 3 to 8 pounds higher readings than this unit. At this point, I have idea who is right. But given that under inflation is generally a bigger safety and performance risk than over inflation, I suppose this unit errors on the right side, assuming it errors at all. It's closest to the old-fashioned mechanical truck gauge that I have. I use it for both truck tires up to 120 psi and down to 25 psi for one of my vehicles.Also, when you take a sample, you have to it on the valve for a couple of seconds. You get an initial reading, and then it climbs by a half pound or so over the next second or two before stabilizing.Unit is extremely robust in construction. Tank-like. Gives the impression of professional, bulletproof construction, but only in time will I know if that's real or just appearances.Edit; I've had this gauge for almost a year now, and I've concluded that it's essentially useless. At the beginning, I was disappointed that its readings were very different than my other gauges, but I assumed it could be right and my other ordinary gauges were wrong. But I was clearly pumping my tires up a lot more than before when I trusted this gauge. Then, after six months of trusting this gauge, my F-150 tires began to wear in the center, a clear indication of over-inflation. I finally took it down to a tire shop when I was replacing the tires and had it checked against their calibrated gauge. This gauge read 5 to 7 pounds low. Also, it's not reliable, with the reading bouncing around by 2 psi on repeated tests. Which means it's worse than useless. I've reduced my rating from an initial 4 stars down to 1 star. It's still a tank, but you can't trust the readings. Very disappointing.

Works good but over time, dust and dirt gets inside the line and causes the gauge to not hold the pressure reading.Cleaning it out will remedy that and if all the tire valves that you check are always clean, then there shouldn't be any problem.

this feels really durable and seems accurate and just feels heavy duty. but I'm very disappointed in the lack of instruction there were with this gauge. i was pulling my hair out because it was not in the box and they had to email me them. i feel there should be a hard copy of instructions in the box. i do feel there are better gauges on the market cheaper and even more useful and less bulky while being just as accurate.i did receive this at a discount for my unbiased review.

I use it for aviation. Its better than higher priced ones and very accuarate.Thank You for a GREAT product.Will spread the word.

Didn't work and I'm outside of return period. I bought this four months or so ago and used it on my 22.5 RV tires for the first time on 4/23/16 (don't ask). At times the unit appeared to register psi accurately then it wouldn't read at all. When I got down to the final 2 tires it read in single digits. My back up tire pressure gauge read the air pressure on the same tires at 105 psi. I tried to return but found I am outside of the return window of 30 days. I'm not sure whether somehow the gauge switched to a metric reading and I have no instructions on how to check. I'll play with it and see if I can make it work. Instructions would be very helpful.

I received the incorrect item the first time. Made contact with the seller and the problem was solved within days. Gauge is high quality and I look forward to using it
