Cheap price cheap product

Purchased a Kymoto XR Ultra Deluxe midsized youth go kart back in november 2016 for a Christmas gift. Put everything together as instructed. With in a couple of hours of driving on christamas the bolts in the rear tire came out. After using different bolts and nuts to fit the wheel on the hub we where back in business until several days later when the muffler cracked at the weld causing a loud noise and the go kart to back fire. Contacted motobuys in January on the situation and the parts needed. They gave me the run around and empty promises. After several reports with them the finally decided to send me a price list on the parts I needed after my warrenty was up so sure I bought them for my little girl loved riding the go kart when it was up and running properly. Once the parts where received and assembled properly after several of hours of driving around the muffler cracked once again. After having someone to weld it back together for me we where back up and running until on May 8th 2017 a little over 4 1/2 months of purchase and approximately 200 hrs of drive time the rod that is attached to the steering wheel and front tires which is only held on by a small weld broke while driving. Luckily my 14 year old son was driving it at the time and was pulling into the drive way when this happened. Just letting peole know if you buy something cheap expect cheap product that could seriously injury or cause death to your child.
