These are some great shades. They are great for high intensity lighting environments.  The UV protection is apparent compared to other sunglasses.  They look awesome too.  I wore them with a black suit the other day and got three or four "Men in Black" comments.  It really does complete the look.  I wear them every day now on sunny days.  They are cheap but they have a very solid and durable frame construction.  I'd definitely recommend them.
