| Our verdict | This unit offers six temperature presets and generous 1.7-liter capacity at an accessible mid-tier price point. It lacks single-degree adjustments, meaning delicate greens must conform to fixed intervals. Check whether internal components or lid inserts introduce plastic into the boil path. | 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. |
