I first got the Power Grips, I liked them but went to eggbeaters after a few months, mainly because I didn't like the hassle of concentrating too hard to get my foot into the strap. Waiting at a red light, the pedal would hang with the strap down, it was not too easy to rotate the pedal and get my foot in while accelerating in traffic. I learned to do it blind but it was still a hassle. The Eggbeaters are dead easy, almost too easy, causing a fall once when it clipped in when I didn't want it to.
