I received free code and go mouse set to review! Upon receiving and opening, I noticed the quality packaging that it came in. Not a flimsy box, but sturdy enough to store the game time and time again without ripping. My 5 year old daughter was able to start programming the mouse after practicing with us through a few of the easier mazes. I loved how the directional cards were color coded to match the buttons on the back of the mouses back. Perfect for younger kids! If my 3 year old wanted to participate we would use extra pieces for him to build his own maze. The pieces were very sturdy! The only con was that the tiles were a challenge to snap together at times!
