I ordered the rose gold. The mug fits nicely in your hand, no dripping or leaks. There's a lock that you can slide up to ensure you don't accidentally pop open the lid. I haven't used it with tea leaves yet so I can't say how that works (instructions say to turn the bottle upside).

It's wonderful. I wouldn't mind a smaller size.

This is a great treat for me as I drink a lot of tea and enjoy the way it keeps it hot until I’m ready to drink my tea.
