Those motorized skateboards are hella dangerous. My dad and I got a scooter and skateboard like 13 years ago, we we're like the first people in San Diego to have anything like it. Anyways the skateboard didn't have breaks and my dad wiped out on a gravel jetti, his g/f had to pick asphalt out of his buttcheeks... He then installed some personalized breaks.
It seems like a legit business. I think this is whats going to really answer the quesiton though. http://search.bbb.org/search.html
