Reviews

  1. I thought i'd write this review just in case anyone was having a similar issue with connecting to the hubs. I've seen some feedback saying it could be the wrong motor, the app or bluetooth connectivity. I couldn't find the solution for my connectivity issues, so i thought i'd share what I've experienced.

    I've just completed stage 1 of the build (the base section) at which point the instruction manual (on pg234) asks you to test the hub connection using the control plus app. I then downloaded the app and began testing the hub. I found the app not intuitive to use as it wanted me to connect to the upper hub which I hadn't progressed to at this point. I tried various things to get to the lower section, but the app simply wouldn't allow testing on the base section. I tried to reach out to Lego via email, but apparently its fairly long wait to hear back from them ~11days.

    So what I've done is to take out all remaining motors and hub and connect those up (randomly). Please see the photos I've attached. Then I've gone back into the app and gone through connection testing. It asks you again to connect to the upper hub first and then you can see which motors are in the wrong ports. After correcting, it instructs you to turn on the lower hub at which point it shows connected to both hubs. It then went through 2 firmware updates for the upper and then the lower hub. After which it goes through a calibration mode. At this point I stopped the port testing as everything seemed to work fine.

    Bottom line for me is the app doesn't work very well, but hopefully the rest of the build goes ok. Good luck to the rest of you! 
  2. I don’t normally bother with reviewing products, however having built Lego for years I treated myself to this beauty. I am still crying with disappointment. Having spent hours doing a pleasurable build it was time to test the motors. I have tried multiple devices both on Android and iOS, gone through pages of websites trying all the tricks and comments other people who tried to get this product to work. The customer service line has failed to resolved the connection issues and I am still in conversation with them.....
