Do not buy anything from these people. I spent $2700 on a XRX Trailmaster go cart and have had a continuing rear brake caliper assembly problem. All I have gotten is an email run around for over a week. I have done everything their emails have asked me to do and have the same problem. I know the issue is a bad rear brake caliper assembly (piston sticks). I asked to talk to a live person and all you get from their inconsiderate phone people is send another email. No one in tech will talk to you personally. I know they are just waiting to tell me that my extended (purchased for extra money) warranty has expired and I am on my own. BUY NOTHING FROM THESE PEOPLE. Their website suggests they are Godly but they are anything but. When I bought this thing, they were happy to talk to me and take my money. Now no one will talk to me. I was looking at Go Carts USA and these people (and in particular the owner of FamilyGoKarts) assured me I would have good follow up service and so I believed him. My mistake I should have gone with Go Carts USA. They have help me with little issues with a live conversation and I never even bought the cart from them. Need I say more as to who you should spend your hard dollars with. One last comment. Their telephone answering people are the most inconsiderate, arrogant and condescending people you can imagine to talk to if you ask for some live person to help you. ALL YOU GET IS SUBMIT AN EMAIL REQUEST. Once you have a request number you can then send more emails.
