Yes, I do need my head examined... from my perspective, I preordered the Raptor 2.0 in December 2017. While waiting I ordered and received, the Backfire2 and Ranger X1. Then in September 2018, Enertion said hey we have the 2.1 ready you can upgrade if you are willing to wait. 20% restock fee if I cancel my order. So, I waited till Feb 2019 to get the Raptor 2.1, Yes, that's 1 year and 3 months of waiting and fully paid for. I should be shot.
At least eWheel is not asking for the full amount upfront and I can get my money back any time and it is only a 2 month ish wait and one year warranty in the U.S. KS16X is $600 more than KS16S. I figured I don't need a collection of Wheels like I did with the eSkateboards. Only getting ONE. LOL
