I would stay away from them. I bought 200 of the 48-speed CDs because they happened to be the cheapest where I was shopping. I reinstalled XP around the same time. I thought I had a problem with XP or my burning programs, because all of the sudden I couldn't burn at 48-speed. Then while using Nero, I noticed when I popped out the CD, the speed would go to 48, but as soon as I popped the cd in, it would go down to 32-speed. All this time, when I was using Alcohol 120, I thought that there was a bug in it's program. Every time I would set the recording speeds to 48 for certain types burning, It would not come up as default. I then tried an Imation 48-speed CD and that solved the problem. So... apparently Eworks CDs DON'T write at the speed listed on the label. That's my experience and 2 cents.
