..be careful that you don't bend them in the middle, as they snap here very easily. .two pairs snap(p)ed here and at the ear peice bracket. ...For the cost, they are a cheap type of plastic,

I would have to agree with this. I had a pair less than six months, before they snapped near the hinge, basically rendering them useless. I'm pretty good generally with sunglasses - so I was a little shocked how my (almost) new pair of Panoptx broke with very little pressure in the wrong direction.

As far as windblast protection goes, they are excellent - but the combination of (relatively) high cost combined with fragile plastic makes it unlikely I'll buy another pair anytime soon.
