If I could give them zero stars, I would. I have placed three orders with them over the past year in order to complete a Taco Frijole minibike, for which they are the exclusive distributor. Every order received was incorrect, incomplete, or both. On one order, after receiving the incorrect part and waiting two weeks for the correct item after RMA, I received the exact same incorrect part. In addition, their customer support could not be more rude or inconvenienced to do their job and service the customer whose money they have taken.
Update 5/18/16 -- Just two curious observations here. The "Jordan T." making responses here replied to my post without any possibility of knowing who I am, further bolstering the fact that these people are unscrupulous liars. The other point is that of their 5 star ratings on this site, one is actually GoKartsUSA voting on themselves (shouldn't be allowed) and another is a completely dissatisfied reviewer that appears to have made a rating error. Their rating is actually even lower than the 11% approval indicated as of this date.
We sent you the parts you ordered, both times. What did you mean to order?
