Quality control
"I have several pair of MOSCOT glasses and these are my favorites. However, the clip-ons came with a lens that is loose rattles around in the frame. The staff were very helpful and offered to have me ship them back to get fixed at their expense. I don’t live near a post office so this is going to be a bit of a pain. I love MOSCOT but I’m disappointed they would send me something so obviously sub-standard. Otherwise, I’d give these 5 stars."
