Summary: Have not tried burning BD-R past DL, nor M-Disc BD-R. No firmware updates or RPC-1 patches available at this time. Should only be used in applications for a --> 11MM <-- high drive. Unlikely to fit in Ultrabook type laptop.
Pros: Reads and writes Verbatim, Sony, PlexDisk, Ritek, Ridata, Taiyo Yuden, M-Disc (DVD), et al. Haven't had it be unable to read a disk written yet, and only rejected media that turned out to be visibly bad. Quiet unless burning at maximum rate, if you're playing or reading does a great job of being ...
Cons: No screws included. Knocked off an egg for that, but it was already at ;) 6 eggs so 5 eggs it is! No software for viewing movies (as advertised). Works with PowerDVD, VLC and MPC-HC just fine.
Summary: This drive was just what I needed for my home theatre pc. It was small and played 3D blurays. For the most part it has done a great job, BUT I have encountered at least on movie it did not like.
Summary: I got one of these inside a Pawtec brand USB3 external kit. Works well, and I am very happy with functionality so far. (burned a 25GB BD-R, 50GB BD-RE data disks, and then watched a Bluray and DVD movie) This is a 12mm thick drive, so do be aware of your laptop's slot size.
