I'm trying to commute to work, and these clips just aren't right for me.
I thought having the single sided clip that could be use with normal shoes would be a good thing, but the right side clip would always spin so that clip side's down. I've noticed that it annoyed me enough that I'd try to look and find out which side the clip is on, which is just outright dangerous if you're riding on roads with drivers.
Also, I've gotten into a few accidents where the clips don't seem to want to release, and I fall over (and this is after the learning period). Let me tell you, that's quite alarming if you have to stop in a hurry, and twist the heel out, and it just didn't quite want to exit.
I switched to a Shimano dual sided SPD, and after the first day, I was a lot happier with it.
