This was a birthday present for my 9-year-old son, and he absolutely adores it. He enjoys the fact that it can be used to play games and that it follows him everywhere. He moves it about without issue on the hardwood and carpet. He's had a lot of fun learning new thing.
Miko is a great idea because it helps children learn a lot of useful and interesting things. I see this toy as is an investment in my child's future. I think it would be better if it had multiple languages, but maybe we will see that in a future update.
