Though the band is certainly functional, the stitching is not very durable.  After wearing my watch with it for only a day, the stitching on the hanging end of the strap started coming loose.  It doesn't seem to have affected the function of the band, but I don't know how it will hold up in the long term.

As for the pros of this band, it's comfortable and can hold even very large watches - I use it with my Seiko Monster and it seems that the band is big enough to hold a considerably larger watch.
