I like expansion watch bands because I don't like dealing with buckles and clasps.  I had been having trouble with metal bands eventually  turning my wrist colors, so I was drawn to this.  I ordered it in black and white, and I love both of them!  They keep time well, and I've had no trouble with them.  I'm thinking about ordering another one or two in different colors, but two watches is probably enough for anyone!  Great price, good quality!
