Product seems to be made solidly and has performed properly thus far. Long term use is TBD at this point, but I don't foresee problems. As a Quality Engineer in past professional times I have seen and evaluated many gauging systems and this one seems to pass the initial sniff test. The follow up from Jaco Corp has been tremendous (without any prompting from me) and I love the fact that the gauge was designed and produced according to globally accepted industrial accuracy standards. I will continue to look to their products first when I look at gauges.

Very nice gauge. Works very well. Outer shell is a plastic covering that helps grip the gauge and protect the inner part of the gauge, the pressure adapter is a swivel so it can rotate 360 degrees. The button on the side allows you to get a reading and hold the reading while you look at the gauge, then release the pressure to start again with the button. Size is small enough to fit in a pocket, but not something I'd carry while doing activities unless I had it in a bag, or a compartment.

I purchased the 100 psi version for checking RV tires. The readings at 65 psi were spot on when compared to a high quality, fluid-filled gauge. The swivel head requires a little extra effort to keep it positioned on the stem. I understand the thought behind it, but I'm not sure if it is worth it.

Someone complained about the bleeder valve not holding the reading, but that is not the intention. Its purpose is to bleed off air after over-filling. Still mine held the reading for almost an hour - long enough to make a mental note to clear the last reading before moving to the next tire.

This tire pressure gauge has worked as it should and is made well for the price. I see it lasting for as long as it is taken care of and I would definitely buy it again. I've had a few communications from JACO customer support making sure the product met my expectations and gave me a contact should I ever need support! If you are looking at this for your motorcycle, you may want to consider getting the pro version (with the extension hose). The angle makes it hard to get to streetbike tire stems (though you can do it). It works excellent for my truck and wife's car.

Sturdy, compact and efficient. Those are just three of the four words I would use to describe this gauge. I think everyone should have one of these. See, you can get one of those pen-shaped ones that will achieve just about the same thing. You can check the pressure, then flip it over and use that little peg on the back to release some air pressure, rinse and repeat. Heck, they even come with a pocket clip so you can carry it around in your shirt pocket like a Tire Pressure Boss. But the key word there is "like". If you want to be a real TPB, you need a JACO Superior Deluxe Tire Pressure Gauge.

I'm not sure what makes it Deluxe. Maybe they have a whole line of these, and the model below this doesn't have the PRV on it or something. But I do know what makes it superior. This, friends, is a high quality tire pressure gauge. It has a rubber shock guard on it. It's sturdy and rugged. It looks like it could take quite a beating. It feels good in your hand, and seems to be the exact right size for comfort and utility. But most importantly, it works. And it's accurate.

The fourth word I would use to describe it is 'red'. It's red underneath that shock guard. And that's just an added bonus, because it matches my Jeep. I thought the ladies loved me before, when I rode around in my Jeep with the doors off. But now, with this SDTPG peeking out of my shirt pocket like a TPB, the ladies can no longer help themselves.
