The actual set is awesome, the fact I cannot run it on a Chromebook, bearing in mind that Chromebooks are quickly becoming the educational go to in terms of laptops, for at least young children is a bad miss. Baring in mind both our Chromebooks can go into tablet mode, the machine specs are better than the min needed (albeit running latest Chrome os), can install android apps and work with the boost hub (the scratch integration worked perfectly) feels like big miss.

Like all of the other recent reviewers, it would not connect no matter what I tried. I lost an entire day and had a very upset child until I happened to read the comments here in the Play Store and following their instructions I was able to update the firmware and connect. Lego, why have you not posted some better troubleshooting information? Why have you not kept the device guide remotely up to date? You still list it as being on the Amazon store, when it isn't! Very disappointed, Lego. :(
