I have 2 Segway Ninebot Minipros. One works perfectly and has only 49 miles on it, battery's incredible, but can't get the headlights to turn on in the app. But other that that it's great! The second one I have works in the app with the Bluetooth controller but when I stand on it and try to roll forward it falls to its face and beeps a few times. Second one has 180 miles in pretty sure it's a super easy fix like a software update but not sure. I have chargers for both also. If these things are your thing than this is the deal for you! My loss your gain.
