Review on HUANUO Adjustable Laptop Stand Riser For Desk - Fits Up To 15.6 Inch Notebook, Mesh Ventilated Cooling With 8 Tilt Levels For Improved Airflow & Ergonomics by Haji Anderson

I like that you can change the angle of the slant making this great for tables/desks of different heights as well as different laptops. I have a work laptop and a home laptop and can change it up depending on the device to create the most ergonomic setup for my current "workspace" (using an informal dining table right now). Previously I would get headaches after using the laptop for about 30 minutes or so, but this gadget has helped improved my endurance with reduced symptoms.The thing I don't like is that it is bulky for carrying purposes. I initially was taking this to/from work in a bookbag with other things and it really increased the bulk. So I just leave it at home. Perhaps getting another one for work would be a good idea except I have a shared work space that is used by others on different days.
