On the plus side, these clips are pretty solid. The handles of the largest in the group are quite difficult to open with a small hand due to this strength combined with a wide handle. On the other hand, the orange-colored plates on the clamping part come off very easily. They're easy to reattach, but if you attach and detach the clips frequently, you'll spend a lot of time finding and replacing the panels every time they fall off. They need to rotate so they can't get stuck. If they weren't, they would be very good.
