I use the cable as a connecting cable of my external USB 3.0 hard drive (2 TB) of Intenso, it is part of my carrying bag Cozy LaCie. It is therefore used by me for the mobile use and does a good job. The blue color like me, because the cable thus settles from most other cables. It is with me while in use 2.0, but it should provide satisfactory performance in regular operation (3.0).
If I can run it at times USB 3.0, I add here my experience it.
