I received the Code & Go Robot Mouse Activity Set free as part of a chat pack. I like the idea of a toy that introduces the idea of coding. The product was easy to setup and operate. It came with a set of challenge card. The first one was incredibly simple but they did get a little more complex from there. The cards held my son's interest for a little while before he started to do his own thing with the set. I think that the basis of the toy is good but that it needs more. There are only 20 program cards. It would be nice if others were made available. The problem solving involved is good. After setting up the maze, you need to determine how to get the mouse through it. The actually programming isn't much more than pushing a few buttons on the mouse depending on what direction you want it to go. It is rated 5 and up but I don't think it would hold an older child's attention for that long.
