Desktop clutter drives me mad, but clients love working off these small USB or Thunderbolt drives, so I often have piles on my desk, wires everywhere, ugh. Not anymore with this shelf! I keep 2 drives on there at all times, a big CalDigit for my photography, and a smaller USB drive for TimeMachine. And then it's a revolving pile of client drives. The shelf slides on super easy, and since those cables are usually super short, they hook up to the back of the iMac super easily (or my thunderbolt dock on my desk). These butler shelf serves a great purpose and while you hardly ever see it, it's totally worth the purchase.
