Query: Finicky & Not Mac Friendly!

This CD burner is poorly designed with the cables connected to an unstable plug that connects to the drive. While this allows for USB and Firewire connections, given the correct connector, the connections are unbalanced and disconnect often. The burner was not at all Mac friendly, as I tried on several different systems & OS versions - nothing but coasters. The burner is also very finicky about the brand of CDs, and would not burn the manufacturers brand included with the product. Support was not helpful in resolving issues, although I found many many others with similar issues and support was in the form of "you are not alone". I did not ever get this burner to function correctly and eventually bought another brand. My opinion is that new or used the Iomega Predator is a piece of trash ~
