I have ridden Look pedals for many years and so buying a new pair for my new bicycle was a given. That said, I wasn't planning to spend this much for them, but I'm very glad I did. These are smooth, easy to clip into and out of, and have a very firm platform.
I like the larger pedal base, which is noticeable while riding.
Clipping in is slightly more difficult than my older Look pedals, but unclipping takes a focused effort. The two carbon springs are stiff, too stiff in my opinion, even with the lightest one.
I really love the light weight and ceramic bearings. The ceramic bearing really allow for more ease of spinning. Easy to get in and out of and have flexibility of stiffness in the step in and out resistance.
