Along with a cable box, you'll also get a cable sleeve, four cable clips, and six cable ties.
Promising review:"This thing is amazing and really cleans up everything. The box was enough to fit my power strip, every cord plugged into it, and other cables that had excess length. Makes a big different to the look under your desk. Comes with a cable sleeve you can use to route cables together so it's not 20 individual cables coming down your wall. It does come with four of those sticky cable dots which are more useful than you would think. I used to not care about cable management because there were just too many cables to do anything with and many just barely reached. But this is totally worth it as the box alone will hide like 80% of the cable clutter alone. I went from over 30 cables to around 20 cables as I have upgraded my setup. This is definitely worth the money and everyone should buy one." —Matt Truffle
