The device is actually very good. Screen, speed, SSD everything good. I have a I5 128GB SSD from the side just fine. But after only 3 days first involuntary wireless dropouts. Difficult to understand and the icon at the bottom in Windows is always at full power. I think a number of people with this problem in the network, only on the wireless AC card, older equipment with the Wi-Fi card and "N" standard do not have this problem. I use the device now returns to the original state, it is then still non return shipping. Schade eigentlich- Ultrabook I liked ...
