I know a few techs that tried them out, they do alright for awhile but don't seem to hold up in a pro environment. However at $19.99 for an air ratchet keep a spare and get a new one I guess.
I think they'd be fine for a weekend warrior.
I've never really cared for the Snap-on air tools even though most everything else in the box is Snap-on, including the box.
It's the triggers, always felt like either off or on, I could never manage to modulate the throttle. I've always used IR impacts, Mac flat air ratchet and grinders, last thing I got was the new Matco reversable cut off tool, being able to toss sparks either direction is nice.
being an ASE Master Tech and having to use my tools on a day in and day out basis, i've come to learn, you get what you pay for, I own either Snap-on or IR air tools...
I made my first visit to Harbor Freight Tool yesterday. My worshop is now built, and I was looking for some nice tool storage options.
I spent almost an hour in there and ultimately left without purchasing anything. The longer I was there, the more I felt like I was at a flea market. I don't think there's a single thing in that place made in the U.S. except for the help.
Sorry if that doesn't answer the question, but I don't think I've ever seen such a collection of crap for sale in a retail outlet.
