Title: still love them after a year of use
Review: Great quality and very well designed. I really like being able to open it with one hand and not having to worry about it leaking in my backpack. After using them everyday for a year, they still look like new. No rust or chipping inside like some cheaper bottles. Note, I use them for cold or warm water, not hot coffee or tea. I would not recommend this if you plan on using it for HOT liquids because the opening is really not designed for that.
