CDM Unisex Polarized Fisch Sunglasses

I have had three different pairs of these and they have all done the same thing. The rubber nose piece just falls off, the first pair lasted about a year and the second about 6 months. This last pair was only a matter of weeks (luckily I was able to return this last pair through Amazon). I loved my first two pairs with the glass lenses, Costa does not warranty them or repair them anymore, they offer you a new pair with plastic lenses. Isn't that nice of them? You pay almost $300 for glass lenses then when you need them warrantied you get $130 pair with plastic lenses as a replacement and they keep your glass lenses. What a scam. I need to find another brand that lasts. Convenience store glasses last longer than these.
