Pros: Great value for these blank discs. Burning speed and accuracy is right on the money. No problems burning as long as your firmware of your drive is updated to the most recent version. I burned about 20 discs so far and not one coaster yet. Quality of the surface is just like those expensive discs you'd get with Hollywood movie Blu-rays.

Cons: None that I can think of. Hopefully the more they make these the sooner the price will drop further.

Overall Review: I highly recommend these for backing up your blu-ray collection.
