Nice unit to raise the monitor closer to eye level. It appears to be sturdy and well built. I would have liked to have a more tray-like feature on which to place my laptop to create more desk space.
It brings the monitor up to a more comfortable and ergonimic height and allows for the storage of things underneath it. I used the larger one for years with my single monitor but had to buy two of the Jr. risers to accomodate our dual monitors. I like them all.
