+ Easy to "assemble"
+ Looks great
+ Given the competitor products still quite inexpensive
- Fairly large clamp (the part through which one pulls the strings). A competitor has a much smaller "castle", but for (almost) double the price.
Really great!
Tip: Thread the band asymmetrically, so that a long piece remains. If you cut this, you have depending on the size and shoe nor a complete, long piece for other purposes / as emergency replacement. Threaded to the ribbon as shown in the image documentation, you cut TWO (often long) pieces from, but they are both too short for anything else! Too bad.
