Pros: The reliability of the Ritek/Ridata brand is outstanding. Far above any other brand I have tried. Out of about 1000 burned I have had 5 coasters and 2 of those due to my own errors in burning them.

Cons: I wish they didn't have to put their logos all over the discs. It also seems that not all burners like these discs and they don't burn as fast as the 8x ones.

Overall Review: If you're unable to burn any discs without getting coasters then you should check to make sure that your writer has the latest firmware.

Comments: This is without a doubt the worst KVM switch I have ever encountered. Istead of switching when the scroll lock key is pressed it activates when ANY key is hel down for more than a fration of a second. So if it looks like this message is missing a bunch of charactrs then you get a good idea of what typing `on a machine using this thing is like. Also, forget about rack mounting this thing since the holes `in the hardware do not match up to the KVM unit itself. Well, oneout of the 4 does. All in a total waste of `money and an all around waste of my time
