The cooler is quite large and not to use it only for 15 '' notebooks.
Even larger notebooks are to be secured by, in two positions stabilized holder.
Processing acts not very high (adhesive're all not optimal - only visual impairment).
The stand is sharp (well suited for a table) and scary bendable.
It has to show in the long run, whether the surviving everyday life.
The fan is like other reviews report audible. But everyone overheated laptop is louder.
The support even has a USB distributor (one input and one output), and even if you could easily control the fan by one and unplugging the USB connector is a small pressure switch installed, which makes it more comfortable.
For cooling effect, I can not say much, through the large metal grid and the spacers I go out but before that it is a massive improvement.
Priced at about 15 it would probably only 4 star, but underneath you can I do not really go wrong with this product.
As long as it does not break, it gets me 5 stars.
