Best digital tire pressure checker and inflator out there!
Great product. This is the second one in my shop.
ProsAccurate, Reliable and MOSTLY easy to use!
ConsOnly 1: I wish we didn't have to push the ON button before placing the chuck on a valve stem.

Nice, solid unit
Haven't used it for long, but love it so far. Works great just checking tires without the air hose hooked up too. Nice big display - no more squinting to read tire pressures. Backlight is a great feature too.

About the only thing I'd change with this is I'd have made a way to shut the display off when I'm done, instead of waiting for it to time out. Would probably double the battery life (haven't changed one yet since it's so new).

It's a bit pricey for what it is, but I've had great luck with Astro Pneumatic products working professionally in the auto & small engine repair industries.

This tool is hefty in a good way. Seems to be built solidly. Has been extremely accurate with my 3 vehicles having the tire pressure sensors. Vehicle read out exactly the same as the inflator. Extremely happy for what I needed it to do. Also received much sooner than expected. Thank you Tools Plus!

This is a solid piece of equipment, a definite improvement over the Ascot we were using. The lighted display is helpful in the evening hours and the heavy chuck can be both an asset for durability but tough in some tight squeezes. I do wish the hose was a little longer (but don't we all) so that we could stand at a larger distance while inflating.
Prosdisplay air release solid build
ConsBulky chuck short hose

Accurate and Convenient
First off this site is great, I got it a day or two earlier then expected which is great, would order from this site again in the future.

As for the product, I use this daily in the shop and it is very convenient, measures in 0.1PSI, I checked it with a Matco inflator and my own mechanical tire gauge and its dead on accurate. I also love how you can add air and release air. Keep in mind also that it does not come with a air adapter you have to get one and screw it on yourself. There was one big issue I had with this product that its not getting a full 5 star is the changing the battery method: the 2 bolts on the back for one are hard to see since the grip gets in the way, plus I used like 3 different screwdrivers to try to take it off which they must of used lock-tight on those bolts because it was hard and I pretty much stripped the head of the screw. I ended up taking the digital screen out of the grip with the allen screw thats on the trigger that way the grip was out of the way and it was easier to see the screws, but it still took time. I hope the next model of this tool has a better battery spot, or they just leave the screws off so you don't have to fight to take them off since they are overtightened.

Overall it is a tool worth the money, and I would recommend it to someone that has patients on the battery assembly.
ProsAccurate, convenient, easy to use, adding air and releasing air trigger, price, great shipping, 1 year manufacture warranty.
ConsBattery assembly- overtightened bolts, no air adapter, not made in USA

Quality Tire Inflator
I am really impressed with the quality of this tool. This is my third pneumatic tire inflator and appears very well made. I especially like the swivel hose and the ability to inflate and deflate with one tool.
ProsLarge LED meter Swivel hose Brass locking connector Can deflate/inflate with the tool
ConsBattery installation a bit tricky Lever deflates a little air upon release

Love it
Love this tool. Changing the battery was very easy after reading the previous reviews. Was going to give it to my father-in-law for his birthday but was out voted by the rest of the family. He got a new TV, I kept the tire inflator. After seeing the inflator he ordered one for himself. Could have saved the clan hundreds of dollars but they think they know him better than me. Not!
ProsDigital display and one lever inflate/deflate.
ConsNot a thing.
