Love the appearance and size but not easy to use. The lid is extremely difficult to handle. Easily slips out of place. Once the tea begins to steep and lid heats up it's almost impossible to remove without a towel. The cup, too gets so hot you cannot wrap your bare hand around it. You need to let it sit a good long time unless you wrap something around it and then the tea cools off. Poor design functionally. At the very least, a rounded lip protruding from the lid would not go amiss?
