It's a brilliant little time killer guaranteed to give you hours upon hours of fun as it contains 200 retro games built into the device and it comes with 2 years manufacturers guarantee. It does require 3x AAA batteries which are not included in the purchase. I bought one yesterday and have been having a great time going through the old classics :)

With a range of games from shooting, arcade, puzzle and sports, there's a game for everyone. With a mini joystick and A + B buttons, this remote is a nostalgic little number for old-school gamers. Includes a 200 strong, on-board retro gaming library.
