I bought the Stem:bot kit that is advertised as their Kickstarter project, but in practice it is a white-label from a Chinese company. The customer service was responsive until I made the payment… I received a kit with an opened and damaged box. It turned out that the user’s manual is badly written, full of factual and language errors. The software supplied was beyond disappointment. It was just not fit for the age group it was intended for. After quite some research I’ve found the software by the original developers that was well maintained and good quality. With that the kit is finally the fun it should be from day one. I tried to discuss this with SB customer service who were unsupportive and ignorant. Good product from a bad supplier.
