Only thing I would do differently in the future would be to get something with velcro instead of a zipper as it would make things easier to work around an existing setup. The zipper requires you to cut holes in the fabric to branch cables in another direction.
This doesn't have to be complicated. You wrap them around the cables then zip the cable tidy up. Does exactly what you expect it to do. Minor issue with the zip coming apart under a whole lot of cables, but you get two in a pack so it's easy enough to halve the problem.
This product is amazing. It perfectly keeps all my cables together and blends into computer setup. It's very easy to use and the cost is amazing. If your looking to cable manage you personal computer setup, this is one of the must haves for it
