Again the main motivation for this purchase was the strap. And it is quite nice. Silicone and hence soft. Nice texture on the outside. Lots of holes for air and fine adjustment. Also quick release and small notches on the strap holders, so they do not slip.
As I said, the price was worth it just for the strap (with 'free' watch).
Plus they do this watch and strap in a bunch of colours.
