It is supplied rolled up tightly in a box, and "remembers" that shape, making it very difficult to lay flat on the floor as intended. This can be overcome by using the supplied tape in sections to stick it to the floor, but even then I found it a battle to make the cables stay in place when doing so.
Pro
Soft and flexible enough to adapt to environment
Contro
Difficult to keep straight and to have cables stay put
