Good advice. Maybe I just lucked out. I bought mine from Amazon actually and just went with the higher rated ones. I did pick one that was recommended by i3 owners. I forget the source but glad you brought up the specifics. Mine is called the "icar" by a company called Vgate.
A fanatic of all things electric. Ridables like electric ice chests and stand up scooters I adore. Drones like DJI, I root for. I'm a fan of both, but nothing beats my love for my 2016 i3 Rex with Deka World. Shhh, don't tell my wife.
