What to know before buying
Listing details to confirm
The listing gives five programs in its details field but names eight auto-cook menus in its feature copy. The number and breadth of programmes are therefore inconsistent. Its stated 30% more usable cooking space compares it with a traditional 34L turntable microwave, not with every microwave.

Consider the stated 20L capacity, 800-watt output and flatbed layout against your cooking needs rather than treating the ratings as evidence of performance.
