Eric L.wrote a review of MIZU V12 36oz Water Bottle on September 19, 2017
Love the product, but had trouble with the seal. I drink hot water (I know.. I am odd), and when the steam builds pressure inside the water bottle the seal leaks. Love the company and the montra, perhaps I will try one of their bottles with a different lid design.
If you are a drinker of cold beverages only, this does not seem to be an issue.
