Audiovox D1420 4.2-Inch Portable DVD Player with Built In Rechargeable Battery
Battery is a serious issue
I bought this thing for my brother and he used it four or five times.  The battery is \\"defective\\" and needs to be replaced.  I've heard on a number of sites that the batteries are \\"defective.\\"  Don't buy this thing if you plan on using it without an adapter of some sort.  Costs $35 to replace the battery, which is built-in and requires sending the whole machine back.  With shipping, I'm sure it costs over half of what most people pay.  The only thing \\"defective\\" is the machine itself (and the wonderful people at Audiovox).  Other than that it's great!!!
