[EX Q]: I ordered this DVD and received a substitute I never received the DVD I ordered from Importcds (the Vendor). I contacted them and did not recieve any feedback. I can't rate a DVD I have never seen. I didn't bother to send it back because it would have cost me more that I orginally paid for it. In the future I will watch for the name of the person and/or persons I am buying from. I thought they were a good company. I understand a simple mistake but, to not get a response at all is not good businees sense. I spend hundreds of dollars a month on Amazon.com building my DVD collection. I guess I will be more careful in the future.
[EX A]: Negative

[EX Q]: I have purchased three of these adapters and they work well. They will charge a G4 Powerbook while the unit is running. All 3 have worked without problem (sometimes the cord comes loose so you have to check that it is tight). No LED on the connector to indicated charging as with the original Apple adapter. Won't work on the new Intel MacBook or MacBook Pro.

Positive
