Steinborg 20 L 3in1 (1,300 W): what works and what doesn't
What works well
- Grill plate on top: removable grill plate for serving, cooking and grilling, a real extra compared with pure ovens
- Switchable fan: convection can be added, for more even baking of pizza and cake
- Stepless temperature: 100 to 230 °C freely selectable instead of fixed levels, plus interior light and a large viewing window
- Complete accessories: two baking trays, grill rack and handle are included
Points of criticism
- Only 1,300 W for 20 L: rather moderate power for 20 litres, heating up takes longer than with stronger 1,600 W ovens
- No-name brand: Steinborg is not an established brand; spare-parts and long-term support are hard to assess
