Pros: This is an excellent product, much faster than any drive I have used so far. I restored 100+ GB's my files from blu-ray discs and it took only a few short minutes on this drive ! I also like the fact it supports BDXL & M-Disc and also lets you encrypt your files.
Pros: I like that it has a 16x buring speed verses my 2x that I had before this one.
Cons: I picked this one because it listed it came with PowerDVD 10 which it did not. All the programs that is listed in the specs are wrong. The only program it came with was Power2Go 8. I picked this one because it has newer version of PowerDVD of my version 7.
Summary: The drive is perfect. It reads and writes - including 25GB Blu Rays. According to the box label, it will read and write 25 GB M-Disc also. Installed in a standard (half height) drive bay and Windows 7 recognized it right away. Have to jump through the hoops to process the promised $25 rebate.
