Simply made me smile loading up Tetris DX and Pokemon Red on this lovely device. The interface is easy to use, great battery life. Also the controller mould I purchased made the device much more comfortable to use, I recommend it. Basically it's like the dream Gameboy from your childhood, but even slightly better, if you can believe that! If you're considering collecting handhelds, buy this first and you can experiment with a myriad of different games and handhelds, even PS1 games, which run flawlessly. I am very happy with this device. It's about as perfect as you can imagine. The delivery to Europe was very fast and professional, great service!
