If you don't want to spend loads of money on a super hi-tech cooling pad but also don't want to spend little money on one that will break then this is the one to go for, it was delivered within days of ordering, and functions perfectly. It has stable aluminium casing to hold the fans and laptop. It is suitable for a laptop around 12" to 16" and the air goes directly into the vents of the laptop to ensure it actually gets cooled down. Before I bought this my laptop would overheatd and turn off randomly (damaging to the hardware and laptop itself) but when I started using this it no longer happened. It also has a double ended cable one end going into the cooler and another end (USB) going into the laptop, this helps ensure the cooling pad can be carried around without risk of the cable getting ruined, there are also vents in the back of the cooling pad which ensures any collected dust just gets blown out of the back.
