This fan is very effective and completely cools my laptop, gaming mode and especially in summer. Sometimes a little because it heats the hot parts are not quite positioned where it breaks down, but I moved a little notebook. Very portable, convenient and lightweight cushion. the yarn is a little short but sufficient. I recommend a good investment to save your mobile. The fan base is a little noisy but we end up forgetting.
Update a year later, the usb cable dropped, problem seen on other comments
