I ordered a electric unicyle. It arrived quickly but it wasnt the model I ordered. I asked for a partial refund and they gave me $30 back (from a total of $450 cost) so i was kind of happy because the wheel works well. Then i opened the case and discovered that the battery pack is only half the size advertised and not genuine samsung batteries as advertised. I started the dispute process but they ignored my comments and ignored the evidence i sent (photos of battery pack). They said dispute is closed and then dont answer my emails after that. They are dishonest and they dont care! They really honestly dont care! They just make up excuses and lie to you with a smile on their face. There is NOTHING you can do once the dispute is closed at their end. The same seller is still selling the same electric unicycles and lying about the battery size and quality. My wheel works well so now I am building my own battery pack because they wont send me the correct one.
