Who doesn't have a bunch of cables hanging, running, and/or dangling around these days? I definitely do. These seem to work great keeping those various cables and cords in their place, secured and/or out of the way in whatever way you see fit. The magnets are a great idea for easy open and closing if/when you need to move cables from one location to another. The adhesive is what will keep this doodad of an organizer in its place. The adhesive does not seem super strong or sticky, so hopefully they will withstand through normal use. There was not indication as to the type of adhesive (i.e., 3M, Scotch, or otherwise), so I hope these will hold up. If not, I'll be sure to post an update to this review.
