My experience with CB Smarty made me skeptical getting this. But with a 20% off coupon and a return guarantee, well i bought it. I used the smarty for about a month resulting in all of my limbs bruised and skinned up. My knee injury even got infected leaving me with constant injury whenever I pedal. So the cheap smarty pedal had to go. Surprisingly ($$$$) this behaved completely different. It was a lot easier getting out, I mean like SPD easy. Getting in is as easy. My pedal effort seemed to have decreased and accelerating is faster maybe due to the weight. I would give this 5 out of 5 for rating. if you have the cash try it...if you don't like it, just mail it back.
