| Our verdict | The gooseneck spout and digital temperature control provide the exact water placement and heat regulation tea leaves require. The 0.8-liter volume is geared toward solo drinkers or small sessions rather than large batches. The $69.99 price directly reflects the specialized spout and variable heating base. | Five preset temperatures offer basic control for major tea categories, though it stops short of single-degree precision. The integrated glass vessel and removable infuser basket allow steeping directly in the pot. It sits at a competitive price, making it a pragmatic compromise between generic boiling and full specialty control. |
