Pros: They seem to be pretty reliable so far. Read everywhere I try. Good price.

Cons: The surface is not perfect for a marker. The cakebox is kinda awkward.

Overall Review: The reliability is most important after all.

Pros: Good looks, talking stop watch.

Cons: Synchronization is difficult, does total reset or displays error for unknown reason. The drivers are for Windows XP only, doesn't work with W2K. Have to remove the back cover just to plug in the sync cable.

Pros: None.

Cons: They won't read in 2 out of 4 DVD drives I own. The worst media I ever used.
