RCA DRC616N 7-Inch LCD Portable DVD Player with 3+ Hour Battery
Great Picture
I bought this for traveling with my two year old.  I have owned it for a month and my daughter watches it almost every day. In the house, with hands on the screen (I left the film attached), knocking it off the arm of the couch and ottom and the thing still works great. The picture and sound quality are great.  However, you will need to purchase a larger carrying case, for all of your goodies, becuase the one provided is only big enough for the dvd player.  The case is used to attach to you car seat so it needs to have a snug fit and that it does.  I highly recommed this product for adults or children.  Another plus, this item actually comes with a manual, unlike some of the other RCA products.  Good luck shopping.
