Breville the Silhouette LMO420BLK Flatbed Microwave, 20L

The Breville the Silhouette LMO420BLK is a compact 20L countertop flatbed microwave with dial controls and automatic cooking menus. Its turntable-free layout is intended to make more of the cooking area usable and easier to clean, while the 800-watt rating and compact capacity suit everyday reheating and smaller kitchens.

At a glance

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.

The supplied evidence contains only a very small aggregate rating sample and no written customer feedback. The ratings are positive, but they cannot establish specific strengths or concerns. Consider the stated 20L capacity, 800-watt output and flatbed layout against your cooking needs rather than treating the ratings as evidence of performance.
