Polaroid PDV-0700 7" Portable DVD Player
4  stars if you get one that works
We bought the model 0722-7\\" with swivel screen. It has a great picture and the sound was really good. We had spent 40 minutes comparing units at Best Buy before deciding. We took it on a trip and other than a minor time or 2 it functioned beautifully. The whole week we were using it, while waiting for doctors, labs, etc, it played fine, battery life was good and we had no problems. On the way home it started saying 'bad  disc', would start to play then freeze, or just sit. It would only play 'Return of the King' all the way through with no problems. We have exchanged it for another of the same model we are now testing, but if this one does the same thing I will try another brand. When it works it's great, that's why 4 stars; the problems on the return trip made it frustrating and we hope it's a fluke, the picture and sound for the money make this a good deal.  UPDATE: We have used the new unit for three months now and are  experiencing no problems. The picture and sound are terrific and if it keeps this up we will be very pleased. We have used on battery and in the car and it works beautifully. After the first go round with the bad one we weren't sure what to expect but it has been a winner; I did spring for the 2 year full warranty at Best Buy- just in case!
