The glasses never arrived! I wanted to trust the good reviews, but I should have listened to the negative ones instead! Plus, it tells me my package has been stuck in Milan since December 15th, but it never arrived. I had to spend more money to buy another gift, since the glasses were supposed to be a Christmas present! I'm truly very sad and angry.
Plus, if you want to speak to the courier, they make you call China directly, which is absurd, since they can't help and we can't be helped!
