The "2" USB ports. One of them serves as a power supply for the Coolingpad. The need for USB cable with 2 male USB connectors is enclosed and has just the right size for a 15.6-inch laptop that the cable on the left side of the laptop can be connected.
That means you have "only" a USB plug which you can further use, but here you can of course "again" to connect a USB hub to any "unimportant" things such as USB mouse, keyboard (with no loss of functionality), etc. to connect , For me this was especially important since I "only" a USB 2.0 connector on my laptop and have my other USB 3.0 ports for not "waste" would.
The different angles are in my opinion be nice but too big fall, within the meaning of only the first 2 settings can be the laptop still "normal" use (default setting has a very slight angle which is pleasant to write, see picture 5 | First Setting is already "very" raised, see Figure 3).
In the other setting of the laptop is aligned vertically very ... I do not know for what you might need it. (See Figure 1,2,4)
Volume is very pleasant, can even imagine in the same room to sleep with it.
The brackets for the laptop can be left at the default setting of course.
If you want to work in the first shot with it, one can easily hurt when the mounts for the laptop because the edges of the brackets are a bit edgy.
Here I can only say more: buy recommendation!
