Beautiful, practical, soft underfoot and they don't slide around on my deck - although they might fly in a high wind if not secured under furniture. The color is more charcoal and tan than black and ivory.  The rugs all took a few days to flatten out after having been rolled so tightly for shipping - but, they are all completely flat now, and there are no curly edges as often happen with low profile outdoor rugs.  They went through their first big rain storm yesterday, and dried quickly in today's sun.  Love my classy new rugs!
