EXELAIR EX536KIT 3-in-1 Professional Analog Pistol Grip Tire Inflator/Deflator Gauge Kit - 16" Hose, Easy-Clip Chuck, Dual Foot Chuck, and Bonus Venturi Tip - 175 PSI

I own a variety of pressure gauges and fillers / deflators. This is by far my favorite if you don't mind how much space the gauge takes up. I wouldn't take it traveling, but around the shop it's the go to. Being able to air up or down or just check pressure in a dually or just about any other tire is great. It's easy to push or pull to get the right angle and pressure thanks to the long handle with the big grip. The air lever is super easy to control. The gauge is big and super easy to read while everything is hooked up, unlike cheaper or more portable units. Super fast since you don't have to turn it on and off and no batteries to wear out. I've gotten so much good use out of it that I bought a second one after a couple of years for another location.

Works as promised but tip that locks on to valve stem is touchy. You have to play with it to get it to lock firmly onto valve stem

I recently bought my first dually truck, a used 2011 GMC 3500HD Denali DRW, and had new tires installed right after I bought it. I never thought about the tire air pressure until I saw the location of the valve stems on the dual wheels! Luckily, Perfection Tire installed some metal "inflate through the valve stem caps" on the rubber valve stems so I don't have to remove the caps. But I was still concerned on how to reach them. I considered some dually valve extensions but everything I read warned me away. Then I found this product! This works PERFECT for checking the air pressure and filling my truck tires which is critical on a dually! I don't even have to remove the wheel covers! The three things I like most are 1) the ability to check the pressure, fill, or release air without loosing the connection to the valve stem, 2) the HUGE gauge which makes it so easy to read the pressure especially for tired old eyes like mine, and 3) the grip on the air chuck so your hand doesn't slide! This was money well spent and I'd recommend it to anyone who cares about their tires especially if they have a dually!

THE GOOD: There are a couple things I really like about this Exelair gauge. The flexible hose is long enough to make using it with duallies fairly easy. And the valve stem connecter is also quick and easy to use. NEITHER GOOD NOR BAD: While not a flaw, for my use case as a tire deflator, this product is really large. It is much larger than the other similar products I tested. Its size can be an advantage for many uses. For mine, it is not. THE BAD: The real deal killer for me is the fact that I could not get accurate readings from it despite getting a good seal on the valve stem. It was understating pressure by maybe four pounds. It is possible that with some experimentation I could have figured out the exact differential between the reading and actual pressure (assuming it was consistent over all pressures) but this is something I'd rather not have to remember. If not for the accuracy issue, I'd give this product five stars. But providing an accurate reading is the most basic function of a product like this. Three stars.

This is very well built, and the gauge is spot on accurate.

This worked well the first time, the second time was on my viair 300 to test my repair setup. The hose blew out the second time, the hose is super cheap, far to soft for the operating pressures this is rated for imho.

Works great. Use all the time.

Haven't used it yet but I will say that the box it came in and packaging inside appears very likely that this was a returned item that I received. All the parts are there so I will try the item out later today and then post another review.

The hose on this inflater broke on the first use, at 70psi. The rest of it appears to be well made, so I'll replace the hose, but at the price, that shouldn't happen.
