I still have a Zojirushi bottle that I bought almost 20 years ago. It was a "luxury" buy from a Japanese supermarket on a college student budget. Still one of my best all-time purchases. I mostly use it in the winter. I fill it with tea/coffee and toss it in my bag. I've yet to experience any leakage/spillage. The older push-button spout rattles slightly, but doesn't leak and still functions fine.
