We got one of these for my Ds last Christmas- he was 2, but is 3 now. I think we will be taking our DVD player instead. It plays more things. The VideoNow does have volume control, though. The main problems we have had are that the batteries run out quickly- though they should last the flight. We also get an ! on the screen showing that something is wrong, but we aren't sure what. It does skip some and DS has not dropped it that we know of, so not sure what happened there. Lastly, this may just be my child, but he acts really strange when he has it. He will get really made and start screaming for which shows he wants to watch on it. HE'll change his mind several times and just scream. This is in no way normal for him. He watches the small DVD player we have all the time and never has these tantrums. My only concern is that it sould be due to the small picture and the video. I know some kids have issues with Video games and, although it's not a game, the graphics may be close and it freaks him out. My opinion is to just use a portable DVD as they are much cheaper than they used to be. Plus, for the price of the VideoNow and 3-4 discs, you can get one and the screen is bigger and you can play so much more. VideoNow has their owns discs that you can't use anywhere else.
