text: The crack in this picture resulted after the travel mug tipped over on my counter top. The mug was not dropped, it just tipped... I had the mug for only two months before it broke. I bought this travel mug after noticing the metal travel mug I previously used left a strange aftertaste on my tea and coffee. While I can say this mug doesn’t leave an aftertaste, it’s extremely brittle. I think most other ceramic products could have survived tipping over. Note, if you plan to store this in a side pouch of a backpack, be aware the rubber grip around the mug will grip to the fabric of your backpack make storing this mug a fight. Also, the top to this mug is by no means water tight. Do not expect any seal. Last but not least, there is no warranty on this product for accidental damage like tipping over, so when this inevitably occurs, there’s no forgiveness.
