I glued directly on my lap, it's really very convenient. I can directly plug in my various chargers (phone, camera), and a bluetooth key for my keyboard and my webcam. By cons, it does not work all the time. For example, my bluetooth key is not recognized (perhaps a question of settings, I have not tried). What is more annoying by cons is that some USB drives or hard drives do not pass (And that sucks)
Nevertheless, it is really cheap, it's worth it! But if you are looking for the real "performance", we have to put more money :)
