Dennis blew the engine in his new Ski Doo snowmobile. Freekin nice. NOT. We ordered cylinders and greasy parts that came within in a few days in the mail so Dennis and his friend could spend the entire weekend in the gay-rage. One part came wrong, but we called and they told us to return it with no problems. Very nice lady on the phone. I guess everything worked out okay as they got the thing running again. They also offer money back if you send back the old bad cylinders, which they restore. I am sure we will be back to order more before the winters over. Good Grief! Update: It has been over 1 month and still no $ for the refund on the wrong part also they refund $ if you return the old core. We returned the core and parts and called several times but still no refund. They need help with their customer service. Minus 1 star.
