I have successfully purchased from Zenni for a few years. This time, despite sending me glasses with visible stripes (lines) in the anti-reflective coating, they refused to send me another pair while I sent my defective pair back. After waiting week to receive these, I can't wear them, and now I have to wait weeks more, before being able to get some new glasses. Not customer-friendly. I won't be ordering from Zenni again. If you value a great customer experience, I'd encourage you to look elsewhere for your eyewear needs. The days of stellar customer service - treating the customer as I would treat the customer, are gone.
