I bought three different glass tumblers at the same time to see which style I liked best. This is the winner. Smart looking design, I like the all-around silicone (white), like the screw top lid which goes on and off easily. After a short while I replaced the plastic straw with a metal one which to me is more satisfying to drink water out of. I also like that the silicone goes around part of the bottom of the tumbler, so I can set this on top of surfaces without using a coaster. Personally I would prefer to not have the KODRINE name in black letters toward the top of the tumbler. A more subtle logo would be preferred. Still, a 5 star purchase.   Read Less
