I had a PM about the quick release kit. Since I'm not allowed to respond because of my number of posts (seriously?) I'll respond here...
The quick release works really well. I raced quite a few times with the 910 and the face snaps into the quick release band tightly. Put it on after the wetsuit. Once you get to t1, the face comes off and goes on the mount on the bike. Takes about 2 seconds. The empty band stays on your wrist for the bike. At t2 you swap it back. It's easy, it's simple and works really well...
