Kabelhaier

The shark heads clamp onto my desk edge and actually hold the cords where I drop them, so my charging cable finally stays put instead of sliding behind the table. Four in the set was more than I needed, but I've got two on the nightstand now too.

Three of my cords were completely tangled beyond hope, and honestly the goofy shark faces made untangling almost fun instead of a chore. The grip is surprisingly strong, but the little heads are cute enough that I don't mind having them visible on my desk next to my router.

The jaws snap shut with a satisfying click and actually hold three tangled phone cords without them slipping out. I stuck one by my desk and one by the nightstand, and for once I can grab the right charger without playing tug-of-war.
