My kids (ages 6 and 8) were really excited when the Code and Go Robot Mouse arrived. They had a blast making their own mazes for their sibling to try and solve. I love that it teaches them some basic programming and problem solving skills without having to use a phone or tablet. I feel there are too many toys out there now that require a screen to use them. The kids really enjoyed this and didn't even realize they were learning. The main reason I only give this toy 4 stars instead of 5 is the limit of 40 actions for Colby at a time. While that sounds like a lot in theory, my kids would very quickly hit this limit while trying to make slightly more complicated mazes. I received this product to try and review for free.
