I really like the auto-adjust feature of these clips, but after a few months of use I found that they are not as strong as their regular non-self-adjusting clips. Part of the self-regulating mechanism broke, rendering it unusable after just a few uses. I've noticed that several other reviewers have had this issue as well, so the buyer should be wary. for adjustability is high, but for heavy use I can't recommend it yet. Also, the pivoting clamp plates at the ends of the arms were not flat…
