this be a great find for we aerobic program . it be very sturdy , yet it be small enough to fit inside we equipment closet and the dumbbell stay organize ! I have to say - the folk at Amazon really help out . at first , this be go to cost $ 140 for shipping alone from any other wholesaler\/retailer . Amazon come to rescue by find it for I in they supplies and they ship it for free with Amazon Prime . Amazon be great !
