December 22nd 2016 order #3170 well first of all it took six weeks to receive the hover boards thank god they made it before christmas. One hover board worked color red but the black one did not. Right out the box as soon as you turn it on, it was like a jumping jack fire cracker very aggressive, leaving track marks all over my kitchen floor. After talking to hover board closeout and them running me thru calibrating the board which did not work i asked for an exchange. They said that they were backed up on printing labels and i will receive a email to print out a label to send it back. 6 months later no label and they changed their number.
