My glasses were lost in the mail, and when I called Zenni, I reached a call center overseas that was eitherunwilling or unable to assist me. In fact, the representative insisted that I conduct my own investigation to figure out what had happened to them. Worst of all, my glasses, for which I paid $70, were of shoddy workmanship. They're so flimsy that I worry that they won't last much at all. Don't buy from this company!
