So I'm a Costa guy, they are good solid glasses. I'm not easy on mine but try to be but always seem to find myself doing something stupid to em. Anyhow bout 6 months ago had my favorite pair on top of my hat when I was brush hogging. I leaned my head back for something and they fell off and went thru the brush hog. They only took a hit to one earpiece that it cut off bout halfway to the ear. I've been using em occasionally or using my others which I don't like that someone gave me for same reason. Anyhow been looking for deals on em (I never pay costa prices for em) and came across a place in NY called Jomashop.com. They had my fantails for $70, so I bought 2. Waited til I got em to make sure it all was legit and I got em the other day. Super happy, with the deal and shipping time. So if your looking for a bargain for Costa's check out Jomashop.com.
