I've fallen 2.5 times with my clips, all in the first week or two of getting them. Once I turned in front of my Dad and he didn't hear me say I was going L (to head to the bathroom) so he ran into me and I just went over (my fault!). Second time I leaned just a hair to the clipped in side at a traffic light, lost my balance and over I went! My pride was left on the asphalt for those at the light to see!. Third time was almost the same...lost my balance while stopped. My co-worker happened to be next to me and caught me (thus the 0.5!).

I think a few tumbles are pretty normal. I have not had any incidents since putting them on in March. I use spd pedals so I don't have to worry about them being right side up.
