This laptop table is exactly what I wanted, looks great, appears to be sturdy (time will tell) and takes up a lot less space than a regular desk. Assembly couldn't be easier.
The laptop table comes with four clear plastic 'feet' that you're supposed to stick underneath the bottom glass plate, the type of feet you usually find on glass chessboards etc. I recommend throwing those out and buying self-adhesive felt furniture pads (available from most hardware/household stores for £1 or less), which are less likely to come off and because they are larger than the tiny 'feet' supplied will give the laptop table more stability.
If you intend to use an optical mouse with your laptop (as I do), remember that optical mice don't work on glass or reflective surfaces so you'll want to use a mouse-pad or trackball mouse.
