Family Go Karts review: Gokarts

I purchased two gokarts assembled by Jeff Backer. One kart worked, one had a deflated tire and steering problems. I t was used once.
I asked this Jeff backer who seems to be their only employee to help fix the problem. He did nothing. This went on for a very frustrating month.
This company says you can return items. Not so. He refused to take the gokart back knowing it endangered a seven year old.
I will pursue legal action against him and his company.
I will contact the state of Minnesota to ask them why they are allowing a company to endanger children.
