The Fellowes Professional Series Laptop Workstation w/USB lives up to its name. It is very professional. The riser is made from high-quality material, adjusts very easily, and holds my oversize laptop very securely. The rubber feet grip my desk surface securely without the need of any nonskid material. I worked in the text editing field for several decades (!) and switching from desktop to laptop has recently become increasingly more challenging as bifocals and aging eyeballs have entered the picture. Buying a laptop riser was way overdue. When I saw this one, I knew I’d found a winner. At its highest setting, the riser brings my laptop’s screen to eye level, so my posture is greatly improved. Because the riser is designed to be an ergonomic accessory for a laptop, customers should expect and be prepared to use the riser in tandem with an external keyboard and mouse. There are no stability issues as long as the unit is used as intended. Doing so has made using my laptop enjoyable and comfortable. The additional benefit of having a built-in typing stand for little jobs is a very handy feature. Okay, there’s almost always room for improvement. Here’s what I came up with: 1. Upgrade the USB housing from plastic to metal (the plastic doesn’t feel professional) and include the USB speed identifier on the unit (1.0, 2.0, 3.0). 2. Do not attach the USB hub to the base unit. It interferes with being able to flatten the unit for travel. (I keep my USB hub free to move around where best needed depending on what’s being plugged in.) 3. Revise the printed diagram instructions by rearranging items “4, 5, and 6” to “6, 4, and 5” since 6 shows how to release (open) the unit from its packed/flat position to the open/usable position. That’s it. The three "cons" are very insignificant. My primary reason for purchase this product was for the riser itself, and that’s perfect! Thank you, Fellowes, for always making outstanding products.
