I wish I could give this more then 5 stars. This concert tour was Tina's best concert. I almost did not buy this because I own this on video. When I recevied it, to my surprise, the DVD has four extra songs on it then the video. The songs are "Wildest Dreams" "Let's Stay Together" "Something Beautiful Remains" and "Better Be Good To Me" If anyone caught Tina on this tour, here is your chance to own the "complete" concert for ever!

I purchased this adapter to replace another PS-AC4 that worked for about 18 months before going belly up. This one lasted two weeks. I called MacAlly and quickly got an RMA number, then I overnighted the defective item to them. That was ten days ago, and I'm still waiting for the replacement to arrive.
