I love mine.
Re accuracy: it's a fun plinker, but the plastic receiver is pretty flexible. For example, I get a different impact point if I shoot it Highpower style (standing with support arm under or just in front of the mag) vs 3 gun style (support hand out at the end of the handguard). Unless you're shooting carefully off bags I think that's likely to limit practical accuracy a little.
"Most 22lr magazines have that button exposed to help with loading"
AFAIK all the S&W 15-22 mags have the button (unless you're talking Black Dog's 50 round drum), but many 22LR magazines for 22LR AR15's (other than the 15-22) have solid sides.
