The main difference between the SandBell and SteelBell is the density and size per weight. For example, the diameter of a 4 lb SandBell is 9 inches. A 9 inch diameter SteelBell weighs 10 lb. A 150 lb SteelBell is the same diameter as a 50 lb SandBell.
Another difference is the increased amount of dynamic shifting inside the bell, as the SteelBell is shifted (the steel shot moves more like a liquid than sand, shifting more quickly than sand). Due to the combination of inertia and shifting steel shot, a 20 lb SteelBell feels and responds like a much heavier weight sort of like the difference between picking up a sleeping child and one that is flailing. This shift challenges balance, coordination, core response, and stabilizing muscles.
The SteelBell is safe like the SandBell. It makes for a great kettlebell and medicine ball replacement because you can swing or throw the SteelBell with maximum effort without fear of injury to self or others. No more worries about hitting your knees or ankles or jamming a finger.

Beyond the amazing functionality and multiple applications, the SteelBell boasts a patent pending fill mechanism (called a 'Ngazzle' -- pronounced nozzle) which allows the owner to fill or remove steel at their leisure.
I ordered a steelbell and was more than satisfied with it. It arrived in a timely manner and was exactly as described. Already having a sandbell I know this new piece will take a beating and keep on going.
