First of all, the keyboard is unusable and only a few keys worked. The mouse was completely smashed, like you would have had to jump in the air and step on it to smash it like this. Apparently many others have reported this, it almost seemed like the mouse box was used as packing material, of which there was almost none. Most importantly, the Windows 10 OS was completely broken and buggy, I needed to system restore repeatedly and eventually directly from Microsoft. This took hours, but at least it is working now. After adding 8 more gigs of RAM and an SSD as OS drive, it is pretty fast.
