My son 12 years old, saved for almost a year for this go cart. when it arrived it have 3 defective parts. It ran for about one hour. I called and was promised all 3 parts within 5 business days. 2 weeks later I finally got someone to answer the phone and was told there was no record of the parts being ordered. I re ordered and on the 32nd day 2 parts came. Still won't run! And now the muffler fell off! Product is junk and customer service is worse. Please never do any business with this company.
