The Lego Boost system was excellent for my 8-year old to construct the model from directions (He choose Vernie) and then, after an easy app install, he and my older son enjoyed much more than one afternoon exploring how it worked, using the coding via IPad app, and even making a short movie involving Vernie. I highly recommend it - it's fun for all children. As an educational tool it has some merit, but as I've seen with my own children, it is easy to just focus on the "bells and whistles" of what it can do versus delving deeper into the coding. In that area I would appreciate more guidance (lesson plans, online challenges, etc.).

Thanks for the detailed feedback! 😊 LEGO® BOOST is a playful introduction to programming aimed at younger builders. Our MINDSTORMS® Robot Inventor set has some more advanced capabilities for those wanting to explore LEGO® robotics. 🤓 - Phil, LEGO® Customer Service

Updated Review: the app is good but recommend you turn on your bluetooth BEFORE you start. The app controls won't work or start decently if you do not cut that on first. The instructions are illustrated, but the angles can be a little off on showing the right placement for some blocks. Otherwise, the app does what it's suppose to do and connects with the motor hub just fine.

LEGO Boost is really fun and motivated my love for coding, programming, robotics, and engineering. But sometimes, on the coding screen, I try to find out the controls but the screen that says how it works ends up shaking non stop and is not able to be Interpreted. Also, not all of the commands I put in seem to work. It is still fun, but it gets aggravating.

Hi Anna, we're sorry to hear you're experiencing issues using the coding blocks in LEGO® Boost. 🤖 Could you try removing the app from your device and reinstalling it? Just keep in mind you'll lose any custom custom coding projects. If that doesn't work, please get in touch at for help. 📞 -Keith, LEGO® Customer Service
