This is really a must have item! It's just long (and short) enough to allow a convenient connection to my Stomp. Additionally, the black color makes it almost invisible when on stage. Finally, its very flexible and stores well during transport.
I have used this charging cable, not only with my Stomp unit, but charging all my other Apple units. I appreciate the extra flexibility of the cable and it's strong construction.
I've been using the standard white usb Apple cable, but this is perfect for performance because it is low-profile (being black/grey) and the braiding feels very high quality.
