Ive had these sunglasses for 2 months and have worn them 2-3 days a week.  I noticed today that the coating is bubbling and flaking off on the nose bridge pads.  I didn't expect Prada quality but they should last longer than 2 months. -  I bought a pair like this from another company for 13.00 about 4 years ago and although they are scratched from heavy use (my fault), I still wear them (I leave them in my car as an extra pair).  - These from Newbee are cute but are not durable at all.  Very disappointed in this purchase.
