This is the worst bottle I have ever used. I was trying to be good, use less plastic bottles, buy an "American made" product. But this bottle is so terrible. I hate it so much. It leaks, no matter how tight you try to seal it. This piece of crap thing just leaked all over my notes. What a waste of money. What a waste.Other problems: smells disgustingly like plastic; when you wash it with soap, it smells like the soap. It will even taste faintly like soap. This is so terrible. Don't buy it. If I didn't have a back up bottle, I would go straight back to using regular single-use plastic bottles. This bottle of mine is getting recycled.
