| 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. | This unit offers both temperature adjustment and an integrated infuser at an entry-level price point. Given the low cost, buyers must scrutinize the build to ensure the interior chamber and basket are free of low-grade plastics. Check whether the controls allow individual degree adjustments or rely on coarse presets. |
