Product Review: D-Wings
Cords can be messy. We live in a technological age and almost everything requires a cord of some sort, even if its just for charging. D-Wings from UT Wire are meant to help you organize the mass of cords in an easy DIY fashion and keep them in the place you want them to be. The foam-like D-Wings have a 3M sticker back that allows them to be attached to the surface of a wall/desk/etc with no lasting marks when removed later.
The D-Wings come in black or white, as well as two sizes. They are super easy to use with the peel off back and they form a pretty solid attachment to the wall--although they can be removed by hand without leaving any mark. They are a bit unsightly and bulky, but they can be painted to match your wall and may still look better than a chaotic tangle of cords. If you are planning to use them behind an entertainment center or desk, their appearance is not likely to impact your decision. For the cheap price, they definitely are up to the task of organizing cords and keeping them in place.
