Glasses are perfect,  however I only received a set of four, I paid for a set of eight. When I contacted customer service, I was told I will be sent a shipping label on May 9th to return the four I received, then will be sent the set of eight.  I asked if I could just get another set of four that I already paid for, I was told "the system will not allow them to process a set of four". That is confusing because i received a set of four. Now I will need to get glasses elsewhere due to the fact I just moved 
into a new house and have no other glasses.
