I've so far used this about a week and am very happy with the product. On opening the box, it was packaged very well in styrofoam and additional protection on the corners. Rubber pads are provided to put on the bottom to protect the desk and prevent it from sliding. Most of these standing desks are too large for what I wanted, and this is the exact fit I needed for my desk - give me plenty of room for a monitor, keyboard, mouse and a notebook/papers. It feels very sturdy when raised and being used when raised. It does add height to my desk when lowered, though - 2 1/2 inches - but I just raised my chair a bit and it doesn't bother me.

This was the best price and best quality of Amazon. I am super impressed!

Exactly as they said. Came built and I used it immediately. It fit perfectly on my small desk and has enough space for my laptop, mouse, writing pad and most importantly ... my coffee.

Pros: comes assembled, multiple heights, easy to lift up/downNo cons until recently one screw keeps falling out, but it doesn't seem to affect usage. I've had this for 5 months now

Easy to set up, fast to change, exactly what I expected. Heavy.
