Title: Great until it slips off
Review: I left it alone twice today for less than a minute and I found my macbook on my computer chair (luckily not the floor). I've had this for quite a while and never had this problem. Perhaps like another reviewer said, the macbook has burnt off some of the rubber. Sad, because it's at a nice elevated height, but not at the expense of my macbook!
