Anyone sent in a Tello for repair, if so what did it cost you if you don't mind me asking? Not sure what's the deal with the one I got? I got it in a trade so it's history is questionable. i'm figuring around $20 to ship hopefully both ways, $80 away from buying a new one.
or go to a local electronics store that sells Tello accesories and buy a new battery. That way if the Tello is damaged and the battery is good, you can get a refund.
