The Look Keo 2 Max pedals do an acceptable job as a clipless road pedal. They are easy to clip out of and provide a stable pedaling platform. However, I have found that while they are hard to fault, they don't really excel in anything like Speedplay's do. The Speedplay Zero's I also own are lighter, offer more float, great corner clearance and double sided entry. There really wasn't anything that the Look's were superior at which is why they got the rating they did.
All in all, they do a decent job as road pedal's but simply are not better than other equally priced options on the market *Speedplay*
