Review on Versatile Full Motion Laptop and Monitor Desk Stand by Mount-It! - Ergonomic VESA Adjustable Mount with Integrated Laptop Tray by Adam Huper

Misleading ad - all pictures show 2 levers but actually only 1 and this part is very low tension and cannot tighten the main lever. I've tried several laptops on it and the arm isn't strong enough for even my smallest/lightest. My laptop fell on the floor several times. I was lucky that my laptop screen didn't break (I caught it in time both times). Rarely have I been so dissatisfied with a product as with this one.
