I've had my Look Keo Max2 Carbon pedals for about 6 months now, and love them. Clip in/out is easy, and I've never unclipped when going hard up a hill or sprinting, during my training rides. I've had some close calls at stop signs/intersections, and have always been able to unclip just before losing forward momentum, without falling over. (I still looked silly to onlookers).
