Really fun and simple "build" - probably takes about an hour if you let the kid do everything and figure out the instructions. The remote control is OK, you can do a few things and its cute. Comes with all the tools you need and its a nice little project.
But the mBot app is amazing! Included for no extra charge, and it has a free-coding mode and a game/learning mode that progressively teaches about how to build code structures. Coding project cards included. If she keeps at it, I'll be getting some add-on parts to expand the robot.
Great value for the money. I put the app on an old phone and gave the kiddo free reign to learn on her own.
