Fantastic cup. My tea remain hot even when I take my time appreciating.
I was looking for something durable and not too large to use for my morning coffee and afternoon water while at my desk. This mug is very well made and it can handle both hot coffee and tea or cold water without problems. While the coffee doesn't stay hot as long as in a thermos-style mug, the size of the cup means that it doesn't sit around long either.
It cleans out well -- I have not had coffee stains linger on the inside surface, though I don't know how long to wait to definitively state that it is not taking ANY stains. It works very well for me and I am happy with my purchase.
This is the best portable cup I have found so far. Titanium does not have a metallic taste and does not corrode. It is super-light and hot drinks will not burn your fingers or lips. The volume is great, too.I recommend buying a lid if you are going to walk with your drink.
One of the best products I've ever owned. It's light, very durable and is sized just right for a nice cup of coffee or tea. And, it doesn't look like everyone else's mug. No problem with hot liquids at all.
I'm sure it can be used as other purposes. This cup serves me good as a coffee mug. Coffee doesn't stay just by flushing it under water.
