It works great for what it's supposed to do, move up and down easily, but it does NOT work well for MY needs. The width is much too small for my needs and, for someone who's 6'5", it doesn't go high enough (I don't really blame the design entirely for this). Also, the keyboard/mouse shelf is much too small. Once my keyboard is there, there's very little room for movement of the mouse. Worst of all is less of a comment on the product than it is on the store as a whole: the customer has to pay return shipping if they want to return the product. This is an online store that provides no way to try out their products in person and does not stand (unintended pun) behind their products enough to provide free return shipping. Now I'm stuck with a setup that inhibits my workflow.
