I bought one of these a few months ago. Put it on the Sam Hillborne. And it was off again after 5 minutes. My heel kept hitting the plastic part. Even tried it on the SimpleOne. Same thing. Now it should be noted that I ride most of the time in Keen sandals which have a wide heel.
It is a nice design, significantly lighter than a regular kickstand and the wider base seems better too. But for me, it just did not work.
If one gets down to a blame game, it's going to be error on my part. Not a problem with the design, but with the user.
