Title: Better than the waterbottle sibling
Review: I use this every Texas winter season for my coffee. I brew and drink black so I don't have any problems with sugar or cream clogging up the mechanics. Washes easy and keeps my coffee piping hot and in the tumbler.Contigo did this one right. I have the Autoseal water bottle and it's not nearly as resilient as this tumbler.
