Clips don't fit well.

Just did not fit my visor and do not use it very much. The clips that hold it on need to be able to fit better with mirrors, security features etc.

The clips are aaalmost too big for the LED strip contacts.  Over time, they tend to slip or lose contact with the strips.  VERY frustrating!

They need to redesign the clips, they break so easily... after only a few uses the clip broke off during normal wear.

Works but poor quality clips that take time to attach.

Some clips seem to be smaller in the sense that when I tighten up lock screw that the camera tilts forward or backwards.

The clips that hold the the blinds into the wall / window frame did not fit correctly, had to modify them a bit with pliers.

These suspenders are nice, but the clips are not tight enough and come undone when I am out and about.

They won't let a piece of paper slide into the clips. Really had thought I could put them right to use, but I'll have to figure out something.

Easy to use  but the clips were a little difficult to put on.

The clips will certainly outlast the plastic ones. If they were a little longer they would work even better.

Minor point:  Retaining clips are too small! hard to handle and connect. recommend larger clips.

These are not your traditional bag clips. The spring mechanism and top of the clip fold at a 180 degree angle and it can get kind of annoying. They work, but would not buy again.

The magnets don't stick well to the clips and the metal around the magnet part sticks past the magnet just a bit which means you definitely don't want to move around on the surface of whatever you stick these magnets too.

The clips work well though!

Clips slide open and fall off the cover. When I tackled folded cover edge into the clips to prevent them from falling off during windy weather - they shredded the cover edges.
