Well over the years I have worn out many impact guns. I have had Matco, MAC, Snap-On, and IR.
Of all of them, by far the most durable and reliable has been my Ingersoll Rand. Seems many of the others required frequent service to keep up, while the IR has always been a proven performer. Outside of about 10 sets of hex head bolts, I have owned a "Classic" IR for over 10 years and it still works to this day... Works well even.
Most recently I have gotten the newer IR Titanium series 3/8 and 1/2 inch 700 Ft. Lb'er and I have been most happy with them.
I dont consider a 1/2 impact an impact unless its at LEAST 500 ft. lbs.

"2135TiMAX 1/2" Impactool 1/2" Titanium Duty Air Impactool The 2135Ti set the standard for performance with the best power to weight ratio on the market in its class. The new 2135TiMAX raises the bar with 780 ft. lbs still at only 3.95 lbs.

Update, I don't love that one anymore - too loud. I switched to an Aircat 1150 which is quieter and has more power. I've been replacing worn out IR stuff with Aircat for a while now.
Just out of necessary I picked up a Kobalt from Lowes, with SAE and metric sockets. Been using it years, works fine but I'm not an everyday user either. Take lawnmower blades off the mower decks for sharpening, use it on wheels lugs etc. I have used chisels in it to cut reluctant bolt heads off

I been lucky with the Harbor Freight Earthquake, which is basically a knock off of the IR stuff.. I even tried the newer composite one (another IR knock off) because I had such good luck with the first one and it has been quite a tough little impact. Both purchased when my IR stuff was either stolen or gave up the ghost, respectively. I wouldn't turn my nose up to an IR, but I have never used Aircat before. To be honest I have never even heard of Aircat before, but I will have to check them out! Snap on stuff is nice too, but also requires costly rebuilds. I have taken a few impacts apart before and you would be shocked how much stuff is crammed in there. You would have to be pretty passionate about an air tool to rebuild your own, but I know a guy who rebuilt his own ratchet wrench so I guess it is not out of the realm.
Here is something interesting too, some of these newer electric impact drivers are pretty powerful! I am shocked at the torque that my regular old Dewalt puts out, and Snap On has some really nice ones too! You would be shocked, no pun intended.
The problem with them I think is the cost involved in purchase as they can get very expensive for commercial grade electric stuff, plus you have battery cost every year or so depending on use which often times it cost less to buy a new unit when that time comes - or at least upgrade. So it is much more expensive in that regard. Plus, I doubt a commercial electric impact is going to work that great on things like pressing in wheel bearings or ball joints, and if it did, I'd imagine it would wear quickly under them punishing conditions every day, correct me if I am wrong, because I don't own a big fancy set of the new electric gizmos but many are going that way, I am just curious if anyone has used one in a press or hub grapple situation and what were their thoughts compared to pneumatic.

Was looking for an M12 triple square socket today when I stumbled upon this advertisement for the Aircat tools,
I grabbed a "Black Ridge" 1/2"-drive impact-gun today...It's claimed to deliver 570-Nm torque ( 420-ft/lb ) with a flow-through /consumption of 140-ltrs/min at 90-psi .
It came with an oil-bottle, allen-key, & 3/8" air-feed connector.
It's nice & shiny (lol) as it's body & handle appear to be stainless-steel & has a rubberized hand-grip in modern-flash colors too...
Most places I've ever worked have had "work-shop" impact-guns supplied, that are shared among the mechanics, so I've never had a need for one of my own until now. That said, the mechanic next to me loaned me his old gun to use, so I felt pressured to acquire one ASAP, which is why I opted for this $100:00 special for now...Plus the fact that I don't know where any of the decent tool-stores are in town that are open on week-ends, so I had to use the "auto-barn"-type stores to source from. Yeah, the internet is the best place to buy, but I couldn't wait another 2-3-weeks for delivery either.
Who knows, it may last a week, year, or 10-years, but it did come with a 12-month warranty, so if it can deliver the goods for 12-months without crapping-out, it's bought-me-time to save for a CP down-the-road. CP could be seen as the "standard" quality gun found in most mechanics tool-box's here in Oz. The only thing that's "dodgy" with it so far that I can see is the plastic-knob that sets the torque-level, & slides left or right to decide rotation-direction.
Apparently a CP impact-gun costs around $600:00 down here, so I'd hate to guess what a Snap-On gun would cost LOL !
I thought it worth posting & updating here, just to see how long it lives for, & whether a lesser-priced-tool with a name & warranty can cut-it with the big-boys.
If you'd like a picture, I'll do it, but I don't have one & can't find an image on the net. There's You-Tube vids, but that's the old-model at a guess.

It indeed appears to be the older CP design from what I can see however this might be more of an entry level impact @ 420 lb-ft but the price of just $20 does present some value providing you don't get into heavy suspension or other such work. I think you will find this tool to be underpowered in any kind of heavy duty work but you could always try boosting the line pressure in them circumstances. One thing is for sure, for taking off most tires it will beat the heck out of using a tire iron - or worse yet, having to borrow someone else's.
I have had good luck with my inexpensive impacts ($100-$150) but I always made sure they were based on IR designs (aka copies).
The CP line is entry level stuff, but it can last if taken care of. I have quite a few CP air tools, many of them came free with various compressors I have purchased over the years - some of them CP themselves.
Keep it well oiled and let us know how it works out!

Perhaps you have a different model, but according to the link above it claims that tool is only rated at 230 lb. ft. of torque.
If that is true, you will find that tool to be seriously underpowered in many circumstances.
Perhaps yours is a different model? Do you have a link to the exact impact you got? Might be the upgraded IR design, but usually them hit in around 600-800 lb. ft.
Now days anything mechanic grade will be well over 900 lb ft., what that means is you'll be able to use it for 95% of the jobs where a tight rusted nut will cause most entry level impact owners to reach for a breaker bar. Once broken free, it should help speed things up but most will just want avoid the time and physical wear and tear of manually busting a tight bolt or nut loose - especially if you work on cars all day every day. It adds up, trust me!

I checked-out that link, & the store was correct lol, but the gun I grabbed was it's "big brother", & it worked fine & trouble-free all day today. And I was surprised at how quiet the exhaust is, as I didn't expect that at all. Anyhow, as long as it can crack-off & zip-up wheel-nuts, I'll be happy, oh, & the odd crank-shaft bolt here & there along with those front-wheel-drive shaft nuts.
Yes it's specs are only around 2/3 the power / torque of the cream out there, but surely the 420 ft/lbs will be enough for most "car-stuff", not-so-much trucks. As long as it lasts a while I'm contented. Good clean dry air supply & a daily oil should keep things rolling lol.
I was always going to spend a couple-of-hundred at least on the rattle-gun, but with the $$$ saved, I grabbed a circlip-plyer-set too.
