Pros: none

Cons: I bought three of these to go into some slim DVD enclosures for use with my new Gigabyte Brix machines. They fit perfectly, but wouldn't spin up and just made a repetitive clicking sound. Couldn't install the OS, so they're useless. I noticed as I closed them that the DVD encountered friction. Also, if the DVD wasn't perfectly seated, the drive would put a DEEP scratch into the disc. Destroyed one OS disc that way, but that was my mistake as much as a design flaw.
