I found that the Polaroid portable DVD is well worth buying.  Simple to use and the company has a great customer service department.  The top viewing part swivels and the picture quality is wonderful.  I brought the 7-inch for my husband to use during his chemo treatment and he loves it.  With the dual headphone connector, we both watch movies together.  Polaroid accessories are inexpensive, so I brought an extra battery (3 hrs).  I recommend this DVD.
