It's indeed true that reviews get outdated and thus some information might not be true anymore. There isn't a lot we can do about this because if we were to update a review every time a new firmware was released, it would simply take us too much time. But, that's why we have Club CD Freaks At the end of the review I've written a text that says that people should check out the Plextor Forum to the latest news and user opinions. If you want to find out if the Plextor is for you then read through some of the threads here.
My personal opinion is that when I wrote the review, the Plextor PX-716A was simply not a great drive and it needed work. Since then several new firmware versions have been released and no one can deny the fact that the drive's performance has indeed increased. It's probably the best drive to get when you're into Dual Layer burning. It's a great performer with quality media written at their certified speed. Writing discs at 16x is still problematic sometimes because the drive cannot reach 16x with a lot of media. But, on the other hand this will only be a couple of seconds difference when compared to a drive that does reach 16x. Anyway, I can only suggest you read through the thread in this forum and make up your own mind. If you have more questions, you're welcome to ask them!
