I received the console. It seems okay BUT, on mine there was no sound at all. Also the LCD screen was crooked, this despite the fact that the listing said that ALL of the consoles are tested before being sent. The app is not easy to navigate but eventually I worked out how to return the item with a prepaid label. In the meantime the seller has given zero communication about the return. The only messages I received was several promotions about buying other products...
One of the best alternatives to playing all "gameboy, and gameboy colour games" all on a compact handheld (which also plays nes, md, & cps1!), and you can add more games to it via the TF card.... Also nice screen quality, and option to use AAA batteries or the included rechargeable battery. Handheld (tf card) came loaded with nice selection of games (with artwork showing on the selection screen), and save point on progress in games etc, ... So this is great value for the money.
