For the price, this is amazing value for money. It has a 3 inch color LCD screen, but the viewing angles are not great. The battery lasts for several hours. Even after playing regularly everyday, I only need to charge it once every week or so. The buttons are also of decent quality and provide a good gaming experience. There doesn't seem to be a battery indicator. You'll know the battery is low when the colors start looking washed out and the screen starts dimming. There's a tiny red led on the side of the screen to indicate charging, but it doesn't indicate when the battery is full. Despite some of these drawbacks, for this price nothing comes close. Definitely worth a buy if you like playing retro games like Mario and contra.
