...and slightly concerned about some of the prices on this product for the different colours. One of these for £30? I got mine for a tenner, so that my knees don't get uncomfortably warm while using my laptop. It works well, and it's also designed to a slight angle so that your arms are in line with your hands, so to avoid typing strain (hopefully).
In all, good, but use caution with some of the prices on Amazon.
