Review on Industrial Strength Sticky Back Hook and Loop Tape Strips, 15 Pairs 1x7 Inch, for Mounting, Hanging, or Organizing Items Indoors or Outdoors - Self Adhesive (Black) by Denise Davis

Edit: nothing, the adhesive is weak and literally falls off almost every night, I'll just buy a screw that works on a wire tray exactly the way you think i've used it to attach the docking station, surge protector and power supplies to the leg and bottom of my desk and it works surprisingly well. One strip doesn't work that well on the underside, but two strips feel solid. It's a lot stronger and tougher than I expected, which is a good thing. I would recommend leaving the glue on for a while to make sure it doesn't come off, it came off a bit but I just reapplied it. and let it sit and since then it has been working perfectly.
