Considering the cost of these, I fully expected to receive a product that was somewhat lacking in quality.  I was wrong.  These are very nice cheapies.  Heavier than most I've tried (I have several pairs of this style of knockoff)  These are by far the best I've come across.  I purchased the black w/silver and the tortoise styles.  Very nice. I also purchased 2 of the colored styles...they are not quite as heavy for some reason, but still fine for something different.  I am very pleased with these sunnies.  I was amazed at the super, super fast shiptime.  This was a major plus for me.  I love companies that ship products super fast!  Yay Triple Optic...glad I went w/this company to order these.
