Loved the glasses; however after a few weeks the white ring around the top came loose on 2 of the glasses. I called Wayfair and was told that they would be sending me replacement for the 2 glasses; however when I received the replacments Wayfair sent a couple set of 6 glasses.   
I purchased a set of the same Glasses in 2017; however they were from another manufacturer, these glasses have been great.
