I've had the MatataStudio Coding Set for about a week now, and so far I have been very impressed. I even went ahead and ordered a second one!
First of all, the storage box it comes in is very well made. A friend and I both mentioned independently of how nice a box it is. It's sturdy and easily holds all the pieces. That sounds like a silly thing to mention but it is a really nice box.
The kit itself is very intuitive, and the design is engaging so you want to start playing with it immediately. I was looking for something that would engage both young children and their parents. The MatataStudio Coding Set is simple enough that provides an entry point into coding but also has the depth that would engage more advanced users.
I also really like that the kit came with 3 booklets of suggested challenges to keep kids engaged even after they have mastered the basics.
Finally, the little robot is adorable! You can program it to dance and make music.
The only thing I haven't discovered yet is how long the robot holds a charge and how often I will need to charge it.
