iMovR ZipLift+ 42" Standing Desk Converter

Hands down, the best desktop converter I've ever had. I've had this for about 6 months and I am never going back. Extremely solid build quality. The lifts go up and down with very minimal effort, the release action is easy. The lift accommodates up to 6' 6" tall people easily and comfortably. The weight limit is very high-holds an ultra wide monitor and a smaller 24" monitor on dual gas arms (buy separately). There are 3 precut holes for monitor stands: center, left and right, if you prefer to setup your desk differently. Keyboard shelf holds a full size Logitech mk570 ergonomic keyboard + mouse combo easily, both in depth and width (you won't be doing gaming mice action here, but it's fine for office work). The full range tilt for the keyboard shelf is a nice touch (and easy to change on the fly with the hand tighten bolt). Doesn't shake, even with aggressive typing at full extension. Since this is a larger Z type unit, you do need sufficient space behind you for the outward extension, and, a fairly wide desk to accommodate the unit. I've had several different kinds of these, X lifts and otherwise from other brands trying to find one that fit me as a very tall person. This is quite simply the best unit I've ever had, not just b/c it fits me height wise, but the build quality is well worth spending over cheaper units.
