Well, Pioneer is considered whacky but the Asus also shows very different levels of errors compared to the liteons/BenQs. I would not use it soley as a scanning device since it’s hard for any beginner to interpret.
You are most likely going to be posting multiple threads like: What’s this scan mean? Is this disc ok? etc.
As for just being a nice quiet drive with decent write quality and lightscribe, I like it. But for scanning, it will show very very different results to a liteon. It’s fairly consistent with it’s results, but they are not comparable in any way to a liteon/BenQ.
