Prime Mini Coyote + received defective. While loaded, it does not dismasted. Returned in packaging and presto, a new received at Amazon. Loading idem and it works perfectly. Registration actually encoded month. Then tested on the road. Impeccable as design. It does not take hours to understand the operation and again he told me a mobile radar in action. Tomorrow, I test motorcycle ... We will see in the heat of the relevance of the toy.
