After initial teething problems the unit is working on my HP netbook now easily. The device is also well made and looks also great. My problem was a USB port on your netbook without adequate power. This did not like the USB burner. Brought but no useful error message produced. My not so young netbook has, as it turned out, two different USB ports. Only the left provides enough power for some devices. This error gave me some time to - and, unfortunately, the otherwise very friendly Samsung phone support was not a brilliant idea. Only a slightly longer study of the manual from the netbook brought insight, yet the different interpretations of the USBs had never become relevant. A Y-cable with two USB connectors for PC initially had not helped, a USB left and right of the netbook was unfortunately useless .... This is just a tip, you can not blame the equipment. Too bad I can only find that the DVD drive is not the simplest model of this bag. Already clear who reads the delivery that can not be expected also. But the device is supposed to eventually be mobile - and the surface falls so from chic that were not at least a simple matching plastic bag with a place for the cable to protect the torch really misplaced. Conclusion: 4 stars
