I bought an X-treme electric scooter ATV-1000 for my wife last Christmas (2008). I worked OK after the first 3 trys in January. There was a problem with the controller emitting a loud high-pitched whine, so I bought another controller that was suppossed to have this fixed from the factory. After installing it properly from instructions supplied by X-treme, it hasn't worked since. It keeps burning out controllers and throttles. At one point I had just replaced a controller, got on it to try it, let go of the brake and it came to life with 100% power, throwing me off the ATV as it ran into the garage and hit some cartons at full speed. I could have easily been seriously hurt. The tech staff thinks that everyone is proficient at electronic testing. I spent $1, 000 hard-erned bucks on this piece of crap that worked on the first 3 trys, although with a loud whine. Don't buy anything from these people. Look at reports on the web and the hundreds of reports about defective products arriving with corroded or broken parts and virtually no returns accepted. I can only hope that their home state will enact a class action law suit. I will never get my $1, 000 hard earned money back, plus the $150 I spent buying parts and it still sits in my garage as a reminder of my huge mistake by entering into a purchase with this company. I have never bought anything from either the web or at a store that had the myriad of problems that this piece of ### has.
