The item was superb only challenge it did not have the British (EU) standard charging ports which meant it could not be used in Kenya

GREAT ORGANIZER!
Model: Pop up outlet-black
I got this to help clean up some of the cords around my office space, an organizer if you will. My husband built me an attachment for my desk without making alterations, and this helped clean up all the cords around my desk!!!! This thing works great! It would be best for an office desk with a built-in slot or as a replacement one for any office conference room!
