In spite of the item description, this rope certainly isn't "weighted" -- quite the opposite. The beads are made of very thin, light plastic tubing segments with interior diameters much larger than the rope (so they don't remain centered, giving it a zig-zaggy, disjointed appearance). It's also impossible to achieve higher jumping speeds. Don't be fooled -- as is typical of so many things made in China, this rope is just a facsimile of the real thing.
