Familiarity: I've used it several times
Do they clip in and out well? Yes. But beware that walking in these things is downright scary. I look like an 80 year old man hobbling around in these, being careful not to fall and break a hip. I'll be buying the version with the grips. They do wear out quickly, but buying new clips is cheaper than surgery.
