Just received ab circle pro, while putting it together discovered it is defective, cant screw in knee pad due to metal blocking hole. Called company for replacemnet and was told they cant ship a new one until defective one is returned, it will take 3 weeks!!! I told them to just pick up defective one and credit my card with allcharges since it is defective. They said NO CREDITS FOR RETURNS OR 14.95 trial even if product is defective, DO NOT ORDER THIS MACHINE COMPANY IS NOT REPUTABLE.
