Update by user Jan 17, 2019 My ThinOptics order of 2 glasses FINALLY arrived, taking FORTY TWO DAYS (6 weeks) to fulfill. The lesson here is that you never want to go through ThinOptics to order and instead only order these through Amazon, using their free shipping. Mine only took ONE DAY to get my order using their Amazon Prime program. Original review posted by user Jan 11, 2019 I ordered a set maybe 2 yrs ago and liked them. So I ordered a couple more for Christmas gifts and we're now at 36 days without a delivery as yet. Talked with the customer service numerous times and all they say is they'll look into it but nothing ever happens. I was once a happy customer, but no more.
