I like these for a few reasons.  The packaging is great.  You get the case, cleaning cloths, and the little eyeglass tool.  I like that these are not heavy but have a little weight so I am not afraid they will break if I toss them in my bag.  I like that they help on an overcast day as I wear sunglasses all the time except in rain, I got the clear.  I love that the first person I saw said, I love your glasses.
