Good hunt! It reminds people about old time games. Here is my personal comments on this product as below:

Pros:

• It is convenient and perfect size to carry for playing anywhere at anytime
• No need to give any efforts to understand how to use. It is simple
• Adding a new game is super easy, even you can create your own game

Cons:

• As it is the thinnest portable gaming device, it might not well fit to people with big hands, I guess
