The Leapster Explorer is a device designed for children that the manufacturer chose do devote exclusively to educational content. The device is well designed, my niece and nephew, age 6 and 4 respectively, were able to get up to speed in using the Explorer almost immediately. I was definitely impressed with the ease which with they were able to learn how to play with this device. This particular Leapster Explorer package comes with a strong protective case, a cartridge based educational app, and a card with a redemption code with which you can choose one app from a list of 8 or so online educational apps. While there are far more online apps than the 8 you get to choose from with this card, in my opinion, they are not of the same quality as the cartridge based apps.
