I will admit, I denied myself this tumbler for too long, just because I thought I didn't need it-- but oh my, yes I did! It is easy to use, easy to clean, and best of all- you take take it anywhere. Hiking, camping, lakeside, SUP boarding, running errands, or just hanging at home this has made drinking tea easier and keeps my tea HOT! I am actually drinking more tea with it. So if you like your tea to go where you do, and you like your tea to stay hot, this is a MUST! Get yourself one- you'll be glad you did!
