The Chinese knock offs were sold for $660 from the vender named DREHOUSE. I have been trying to cancel the order for the last month and they just arrived yesterday. The box says “DUMBBELLS” right on the side of it and it is shipped from CA which is not where Nautilus/Bowflex is located or manufactured. I spoke to the UPS driver about not accepting them. They cannot be returned IF opened but the box was ripped open. I looked inside to see knock offs that say DUMBBELL right on the handles. SCAM!
