I got this while I was in Kansas. Actually, my future MIL bought one, they charged for two and she gave me the extra one. 🙂
I used a generic one while
running walking on the treadmill in their basement while I was in Kansas and fell in love.
It keeps cold drinks cool without producing condensation on the outside. A bit heavy, but definitely worth the $11.
Like the SIL said, “You drink more water when it’s through a straw.”
