In all honesty, I'v used couple of them but I havent used em extensivly enough to say they are **** or amazing. They are 12 points impact thin walls, I feel like they could break on 600ft/lb + air impact, then again, they are thin walls, so not much is expected. But if you need a good set of 12 points and are thougher than regular chrome. I would say its a good bang for your buck. Like I said, I'v wrench a little with em and never had any issues.

I haven't swapped out a 12 point yet, and rarely hear problems with the 6 points.
Using these on an impact, you should never have an issue. Now a hand tool, maybe. People tend to forget that impacts are really geared for the on/off blows of a gun, not the straining force of a hand tool. It's easy to think, "Impact, well that must be heavier duty if it can take a gun." But it is a whole different kind of stress.
Sure they will do it, but when it comes to hand tools, I'd rather use a chrome socket that is thinner and harder. For things like reducers an impact grade will generally fail at a considerably lower torque value when driven by hand.
That is where you get your twisting/tearing. Almost anytime someone contacts us with a broken impact reducer it was being used on a breaker bar instead of a gun.
But being a Michigan guy, I try to avoid 12 points on 6 point fasteners. I do have a 12 point set for the occasional 12 pt fastener, but nothing beats a 6 pt impact on a rusty Michigan 6 point bolt. Nothing shreds rusty corners quite like a 12 pt impact socket on an IR gun.
