I knew when I ordered this lamp that is was USB only so that was not an issue for me. It looks great on my small desk next to my Macbook. Provide 3 types of light with just a touch on the base. I chose the white because it give it an "apple" look. Very similar to my Apple magic mouse.  Puts out good light. No set up. Just take out of the box and plug into USB

Pros: Good looking design. Good light. Looks more expensive than it is.
Cons: No cons but know that this is a small lamp. It will only light a desk space, not a whole room.
