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.
This completes my double wall titanium 3 cup collection. The 230 is everything I expected. Excellent craftsmanship, quick delivery. AS soon as it arrived, I washed it off and filled it with the first thing I could see...Ice and Cream Soda :) It keeps the temperature relatively stable. Hot stay's hot longer and cold stay's cold longer, what else could anyone ask for.
I found it to be the best quality, best made, lightest cup I have ever gotten to use.
