Bests & Worsts Reviews from Amazon

Support is helpful and fast, typical wait for email is 2-12 hours for a response. The first time my scooter was locked via Bluetooth then would neither reconnect nor roll the front wheel... I couldn't even walk it 3 miles home, I had to uber. I found that plugging in the power cable forces a shutdown which unlocks the scooter. So problem solved but what a useless lock. **Edit: the KS4 Pro seems to have a much improved design & firmware updates helped further. Read reviews for that one too.
