Casio EV-570 Handheld Portable TV
Battery Eater
This is a very good tv that consumes battery like crazy.  At first, I used the regular AAA batteries and they lasted me way less than the 3 hours recommended.  I started using rechargable batteries instead.  However, after a 5-hour charge, this only gives me a 1 hour play.  I am going to return this product after I go home today.
