I can only assume that the brand’s cult following is buying the slightly pricer bistro set, which has a better-shaped bowl, and they are likely selecting one of Fiestaware’s other mug designs.

We steeped some tea, poured it in the mug and set its temperature to 140 via the Ember app. And then, over the course of about 45 minutes, we enjoyed a beverage that was satisfying to the last sip.
