Poor adhesive

These things are a good size and good selection of colors, but ultimately they're useless if they don't stick. On a flat surface they're okay. However, I put three on a wall to run a string of coax up about three feet and, while they were initially all well-attached, within a few weeks they'd all fallen off the wall. That's one cable holder per foot of cable, which I'd thought was excessive but even then the weight proved too much for these. Anyhow, if you're running cables across the top of a desk or the like they'll probably do fine. And perhaps on a smooth vertical surface like metal they'd stick better, but short of that don't expect much.
