We bought our son this lego robot for christmas thinking that it would be a great introduction to programming. Unfortunately it has been incredibly frustrating for all of us because the app is constantly crashing or malfunctioning. I finally got fed up and cleaned up our kindle fire then reinstalled the app. For the first 5 minutes it worked again, but once again the programming is malfunctioning. Even when we do exactly what it says all of the command lines play at the same time.

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

Update. So I have done all the troubleshooting, and made sure everything was compatible. BUT it seems that the app no longer connects to the device. In fact, half the time it does not even see it in the list to connect to. This happened after the 1.9.5 update. So, it is with much sadness I must say that while this toy was great for 3 or 4 months and worked perfectly, it simply does not work with the app anymore. The new hub and old hub are both not connecting. Update. Lego provided us with a new hub motor. it works much better. the bluetooth connection is a little weak still only going 15 or 20 feet but this is a great toy...and it connects correctly. we mist have gotten a one off the first go round. original: will not connect to hub motor correctly. constantly crashes. brand new phone.
