Sleeving is very well done. Material is very rigid and does not bend well. The cables on the inner side of the bend will not shrink, and on the outer side do not extend. Which causes the individual cables to move out of their "super clean look" position.
Product quality is great. But I am only giving 4/5 stars because the shortest version of this cable (100mm), which I ordered has serious problems when bending it, due to its rigidity. If I were Winkool, I would completeley remove the 100mm products since on their short length, they're too rigid to remain looking 'tidy', even if using multiple cable combs, if they're bent (and they are always going to be bent in real life use.) So learn from my mistakes and always order at least 200mm, even better 300mm. Even if you would not need the length.
