Mintek MDP-1810 8-Inch Portable DVD Player
Poor quality control
I purchased three different Mintek 8inch DVD players and each one was defective.  The screen was so dark on the first one that I could not even see the menu.  The second one had a defective pixel.  The third one worked for about 3 hours and then the screen went dark just like my first experience.  Needless to say, the quality control of this product is rather poor especially since the warranty (which includes labor) with these products is limited to 90 days.
