Weight:
With 272g the softX is more than twice heavier than the Blackroll (118g), but to little more than a bag hazelnuts lifts you look indeed not broken, right?
Material:
softX has outside a softer envelope, but just a solid core as the Blackroll. This is particularly sensitive for people with a spinal anguished the gentler variation. At the beginning of the exercise immediately the hard pressure arises, but it "sinks" by the weight minimal in the first layer, before amn strikes the hard core.
Those who thus already equal'd rather harder even when forking, which should remain at the Blackroll.
Handle:
The softX has no recess on the side, in which one can reach into it. They simply takes for transport as in the arm.
The Blackroll are accessed more easily high.
A very small minus, .. but not really for me a criterion for selecting ...
Care:
Both roles are damp cloth and can be cleaned with disinfectant, without the surface takes damage.
That immersion in water brignt also no harm.
Price:
Currently 7 difference!
The Blackroll can pay its name well.
