- Product Review (submitted on December 29, 2017):
- I love the tumbler and on my second one. My issue is, not with the straw, but with the straw opening in the cover. It wears out overtime and causes leakage. I have to cover the tumbler with press n' seal wrap to prevent leaks when I bring to work, etc. I need to request a replacement cover, the tumbler never wears out.
