Took a very patient employee about 20 minutes to find mine. Try again if you're really that interested in it.
Got to play around with them tonight a bit. Color me impressed (and addicted! )
First I finished mounting my plywood modem/switch/wifi router panel to the cinderblock wall in my basement. After giving up drilling holes with my Ryobi drill (non-hammer) I just left it hanging by 2 tapcons. The M12 hammer drill knocked out 4 new holes in about 5 seconds each on speed 2. The impact sank the 3/16" Tapcons on level 2 no sweat and even ran them down flush on level 1.
When I went out to the garage to put them away I strung together a 1/4 hex to 3/8 drive adaptor with a 3/8 to 1/2 adapter to mounted up a 21mm impact socket and gave it a shot at the lugnuts on my Z. I recently torqued them to 110lbf, and after maybe 5 seconds of rattling on level 3 it spun it off! For comparison, I ran rhe lugnut back on at level 3, let it rattle for a second or two and gave my Ryobi P237 a crack at taking it back off. No go, even after letting it rattle for a while.

The P237 is rated for 50% more torque,, but I guess the stars have to align in the lab to actually hit that nimber. Thr M12 took it right back off without too much drama.
...and to think I was questioning whether the M12 stubby would satisfy me!
