I have used it to burn both DVD and Blu-ray Media with excellent results.
Hardware is good, but programs are so,so.
It works great.
It works very well with no issues and is compact so it's great for use with a laptop.
This is great.
Very slow write speeds.
Crazy fluctuation when writing to 4x DVD-R M-Discs which never exceeded 2.4x speed.
The included BD-R 4x M-Disc wrote, with less fluctuation, at a stable 0.9x.
No, it doesn't truncate, it has you guess what the requirement is...and a little searching reveals others have this problem as well.
If the software doesn't work on blu-ray, the burner is of little use.
