Power on photos a wertigeren impression than in reality. By the time allowed for the first time go out the slide to insert a disk you end up on the floor of the full plastic reality ... ;-) But that is not to us, shrill ?! Following USB3 Hub easily, device ready for use immediately (WIN7 / 64). The burner is not recognized by a PC reboot every now and then. Once power switch off and on, and he's back. According to my previous experience, the device reads faster than average (all formats). With "problematic", ie old-burned or scratched discs I have so far not had any experience.
Let's talk about "supreme discipline", the burning:
I have been close to 30 (mostly non- "brand" -) pieces of silver frittered (CD, DVD, DVD-DL, BluRay, Blu-DL). As burning software ImgBurn came to use. Firing was always at the fastest rate (according ImgBurn).
Result: Although some disc due to the high combustion (- and read) alarmingly high temperature speed leaves the part, there was so far no failure or stuttering.
Should that still be the case in half a year, there is (in spite of the many times invisibility) earned 5 stars.
