Outstanding design and better than I expected
Got the Rolling Laptop Stand, added the book holder and frankly I love this thing so far. Goes exactly where I need it all over the house, stays exactly where I want it, arm extends more than enough (I was worried about that), and holds mouse plus 13" Mac with ease. Good customer service on a question I had (order split into 2 boxes, they responded well within a day), and SIMPLE setup video. Very Very happy with this - wish they had the exact same base in a monitor stand, I would buy that in a heartbeat!
