Something is amiss here. Steel's density is 8.05 g/cm3. Even if the person "measuring" the density included the air, they should have gotten about 2/3 of the full density, or more than 5 g/cm3. A number like 4.15 is closer to titanium, and I seriously doubt the little balls are titanium.
Well, the reviewer did say it's nonmagnetic, so it's not steel. For the price they want for it, it may as well be gold, but that would be heavier, too.
