Bought two 6' round rugs and was thrilled with the bright colors.  Rugs did not match perfectly, but they do the job of brightening up an otherwise monotone area.  Since they are handmade, they are subject to individual parts of the weave coming untwisted and sticking up.  I have an active labrador retriever who helps this process along.  The pieces are easy to twist back into place. Chairs do not roll easily back and forth to my dining area table. Minor problem.
