Picked up the GT3 Pro for my son and it has been great. We live in a very hilly area and it handles everything with ease, and no concerns with battery life. I even use it sometimes, we absolutely love it.
As a ST3 second hand owner, I received a first class welcome with Navee service team trouble shooting a minor problem transferring ownership within the app. The support team came through big time for me. I am not new to riding scooters and must say the ST3 is so much fun to ride with great take off speed and world class comfort.
Bought a navee st3 pro for my nephew. Was cheaper than buying on amazon. I used paypal but was hit with a foreign transaction fee which was not apparent at checkout but still cheaper than Amazon. I will say the communication was very good got updates on shipping and notified the day it was arriving. I will have to update the review once he tries it.
