If you’re looking to purchase Ninebot products online, you may be confused over "who is who?". There are several online stores and most of them claim to be “Official” or even “Exclusive”.
The best way to check if an online store is authorized by Segway to sell Ninebot products is to go to Segway’s website (www.segway.com). On that website please go to the section labeled Dealers. - http://www.segway.com/dealers. It is important to confirm that an online dealer is listed there. If you cannot find an online dealer on that website, something is wrong. Most likely the website is selling old "Pre-Segway" inventory.
It is important to understand that non-Segway inventory is not be covered by the Segway US warranty.
