Reason for not a perfect 5-star review is the lack of color options. Recently colors were dropped to make room for new ones but so far we've only gotten Emerald, which I bought and was slightly disappointed it was nearly indistinguishable from the turquoise color in person. Colors that exist in the tie-dye series that are gorgeous like the royal blue in the Arctic mug and patriotic mug have never been featured solo in a cup and they should - everyone has a favorite color and shade :) the only solid blue options so far have been navy or sky blue, no in-between. Brown hasn't ever been featured either to my knowledge, much to the disappointment of Cleveland Browns fans or people who may want a brown mug for their lodge style bar. Just sayin, color options, try it out! :)
