I bought an AGV XR-2 a few weeks ago, but I just received the Mirror Sheild today.
Overall I like the helmet, but I still wished it were a little more quiet. Maybe it's just me but I've said this about all my past 5 helmets.
The one main thing I really like about this helmet is when I get up into tripple digits my head doesn't bobble around. AGV did a nice job with the aero-dynamics on this one with the wind tunnel.
Here are a few pics.
