3 days ago I received the go-kart a Trailmaster 200xrs from FamilyGokarts. There were no assembly instructions. Spent time on the website and watching videos. They have no instructions about the 200xrs just similar go-karts. I called twice the 2 women over the phone are rude and I was not rude with them. Their support is email only and they don't get back to you for hours. After some time charging the battery next day it does not start. Spent the next 2 days emailing back and forth still nothing. Don't buy from here! Had to call a local shop and having them to fix the issue. Lesson learned don't buy!
