I ordered two hoverboards. One of them did not work. It took their people months to reply to my emails about my defective hover board. I was told to send it back at my cost they would repair it for free and ship it back to me for free. The only thing I had to pay for was shipping it back. It has been over a month since they received my hover board. They claim they never received it until I turned them into the Better Business Bureau. All of a sudden The hover board magically appeared and it is repaired however, they are holding it hostage and refusing to send it back until I pay for the repairs after I was told it would be free repairs. Now they say that my warranty is invalid! Of course it is -It took them months to answer my emails! Do not buy from this company. They sell defective merchandise and do not back up their guarantees. Horrible company. Horrible customer service!
