This is an amazing product that focuses on critical thinking, problem solving, and basic program flow. My children (2&5) both had no problem grasping the concept and both enjoyed solving more and more difficult problems. By the end of the 1st week my son was making his own mazes and having the mouse run them backwards for fun. I have really seen a change in his approach to problem solving in his day to day life as a result of this product. Where he used to ask for help with an issue he now takes a step back and thinks the problem through in a incremental manner. The product itself was very well made and I have had zero issues with it thus far. Full Disclosure: This produce was received as part of a chatterbox campaign.
