It can also - and above all fast - invite other USB devices!
Only the very small and barely audible "buzzing" in the operation leading to the withdrawal of a star. This is only audible when you put your ear close. Otherwise, the device is really great and also looks stylish as when operating a blue LED at the USB plug lights. It is also a further plug for US sockets available.
For those who frequently need to load USB devices Highly Recommended!
