The fit and finish of my MDD glasses are really problematic. The paint comes off very easily, they don't include a plastic cover over one of the arms, and there is rub in transportation and handling. I've had 4 now and every single one has finish problems ranging from deep scratches to missing paint with chips, and rub marks
Sorry to hear about the issues. The iridescent paint on the MDD version looks pretty nice in photos. Hopefully KOO has been responsive with warranty or replacements. The BORA's metallic paint has been holding up well for me with normal use, but isn't as unique as the iridescent finish.
