Title: Good product, impatient consumer.
Review: As a college student, I don't have time to grab breakfast for my morning classes. I just put a tea bag and pour boiling hot water into this cup at 8 AM and I can't drink my tea until 10 AM because it keeps it at that boiling hot temperature for at least 2 hours. So I starve through my class without sippin on tea. In conclusion: great insulator. My burnt lip isn't too happy about how well this is designed. It's also carelessly thrown into my book bag and it hasn't leaked a drop onto my papers and laptop, unlike ALL my other thermal cups. Once also made tea for my boyfriend in this tumbler. I made tea for myself in a tumbler from a different company. Both teas were brewed from the same kettle. We both went into class at the same time and we see each other after our 2 hour class. My tea is actually cold by this point and his is still hot. Proved the difference.
