I bought this cup based on earlier reviews (which were all positive). Unfortunately, I'm very disappointed!! The lid leaks... it's entirely made of silicone and doesn't hold very well on the glass cup, so coffee spills out between the glass and the lid when you drink. Also, the lid has a similar design as a Starbucks lid (but in silicone), which means that you can't close it - the hole out of which you drink is always open. Definitely not a travel cup and definitely not recommended!
