My girls age 4 and 10 both had so much fun with the Robot Mouse! It was a great opportunity for my older daughter to help my younger, and they both thought it was "so cool!" I love that they are getting a jump start on STEM work. Because you can set up the maze in endless configurations the girls didn't get tired of it after 10 minutes like they have in the past with other toys. Very pleased and excited to share on our next playdate!
