Polaroid DPA-07051B 7 in. Portable DVD Player

I did not buy this model but I did buy another Polaroid dual screen portable DVD player and it was a piece of crap.  I had it about a month when it started giving me problems.  It would be working and then it would cut off and restart.  I contacted customer service since it was still under warrenty and they told me to try a couple of things which I did but it still did not work.  I asked if this was a common problem with the unit and was told no, they had not had this complaint before.  (After going on Amazon.com and reading the reviews a few minutes ago I know they lied)  They had me send it back for an exchange and it took them 3 months to send me a new one.  I called several times and was told it was on back order.  When I received the new one it worked for a month and a half, just over the warrenty period so now I have a unit that doesn't work and they want me to pay $85 plus shipping to get another piece of crap from them.  I will never buy another polaroid product and I am telling everyone I know not to buy them either.
