Many, many, many years ago I ordered two sets of metric impact sockets, one 3/8 drive and one 1/2 inch drive. I also ordered their large set of air hammer chisels. Now keep in mind this is way back when the only Harbor Freight was in California. Probably 30 or perhaps a few more years ago. The metric sockets I never thought I would have a need for a "good" set, so I bought some cheap imported crap. The chisels rounded out the order, they were on sale and shipped for free. All three sets are still alive and well. I thought at least the chisels would break or be soft..or the tapered end mushroom. Nope..still as good as the ones from Chicago Pneumatic or Sears. Ditto for the sockets. Some show a little, and by that I mean very little wear in the drive hole, but no more than my Snap-on set that cost five times as much. No socket split it's side out, even when used with an adapter on a 3/4 inch impact. Oh..yes..the impact adapters. Bullet proof. No wear whatsoever..they just got shiny in the drive holes.
Their chip brushes are great..as good as anyones but much cheaper. Their air hose on a retractable reel is great, both the 25 and 50 foot ones. Five years and no leaks or complaints.
