This wasn't the cheapest of the Rewritables available, but after wasting money (and a lot of time) on the CD-RWs from Memorex, I decided I'd give Sony a shot. Sony media is almost never faulty, and since I planned to use these with my MP3 collection for my car audio, it was important that I don't use a disc that kept skipping. 4 out of the 5 Memorex discs refused to be written to properly. At first, I thought it was my car stereo. But my older CD-RWs were running just fine. So, I finally picked Sony. The write speeds are low, but for the use I have, this is just fine.Pros: Absolutely no write issues.Cons: 4x is kind of slow. Industry has rewritables at 16x.
