A hit or miss, some flavours are good and the others, not so much! Since they only limit you to taste test one flavor, order a flavour that you know you'll like.
I liked their oolong tea, taro, hazelnut flavours, but really didn't like their wasabi pea flavour and this other new flavour called something bees.
My advice is, after such a long lineup, order something safe and something you know you'll like.
3.5 stars.
