Each DS functionally works (they read DS and GBA carts, play games, touchscreen works with stylus, hinges are good, picture display is correct) HOWEVER they all have worn or scratched screens, and may also have shells in bad shape. I have tried to take photos of the screens of each one and show this, and taken a video of one of the worse ones so you can see in action - expect scratches on screen and assume these to be in poor condition, despite working and playable. Hence the lower price. Original phat Nintendo NTR-001 in blue. Tested and working. Comes with stylus and USB charger. Screen has also been calibrated successfully. Games not included, this is to show the DS works.
