Title: It does leak
Review: I bought two of these last winter (2011) and have used them heavily for a year.Good: They do insulate very well, keeping the contents hot for several hours. Also, the design is nice looking and very simple to operate.Not so good: The mechanism that opens the flow is a large button on the side. If you put it into a bag where it can bump into other elements I would not advise to buy it as it will leak and get your stuff wet. Otherwise it works fine, for example, if you use it in you car's cup holder or standing in your home/office.Bad: One of the two began leaking a month ago, so I can no longer carry it around in my backpack's compartment. Also, I don't own a dishwasher, and cleaning the lid requires a bottle brush to prevent stuff from accumulating in the moving parts. It can get smelly if you don't clean it with detail.
