I ordered the Hexy the Hexapod robot (previous kit from the people now putting out Sparki ) and mine had serious Q&A problems with the plexy cutting and the used servor's are no way up to the task.
I'm not saying Hexy the Hexapod is a rippoff (price was okay for the amount of hardware) , but it was seriously underengineered and "beta" when put in production.
I'm hoping they do a far better job with that Sparki ...
