What matters when buying?
Start with the controls you would use for butter, then decide whether your other cooking needs justify more modes, a larger cavity or a built-in installation. Capacity in litres is a starting point, not a substitute for measuring your bakeware.

What to check |
Who this matters to |
| Gentle control |
Check whether you can select a lower microwave power level and set short cooking times manually. |
I want to soften a small amount of butter without letting it melt, so I need control over each short interval. Around 36% of consumers would put gentle control first. |
| Functions and worktop space |
Compare the included microwave, grill, convection and air-fry modes with the appliance's external dimensions. |
In a small kitchen, I want one appliance to prepare ingredients and handle some baking without taking up too much worktop. Roughly 29% of consumers would make that combination their primary concern. |
| Capacity and cookware fit |
Measure your regular dishes against the usable interior, shelf arrangement or turntable diameter; do not rely on litres alone. |
When I cook larger dishes or batches, my tins need to fit and the cooking modes need to suit the recipe. For around 21% of consumers, cookware and batch-cooking needs would come first. |
| Features and installation fit |
Check which extras you would use and whether the exact model's dimensions and installation instructions suit its intended position. |
I would rather avoid unused functions or discover too late that a built-in appliance does not suit my cabinetry. About 14% of consumers would prioritise straightforward features and installation fit. |

Questions about choosing a combi
Do I need a combination microwave just to soften butter?
No: if softening butter is your only task, focus on a microwave with selectable lower power and manual timing. A combination model becomes more relevant if you will also use its grill or oven-style cooking functions.
Does higher wattage make a combi better for softening butter?
No: maximum output and the choice of lower settings are different specifications. Panasonic UK & Ireland lists 1000W and seven power levels for the NN-CD88 range, while Russell Hobbs lists 900W and five levels for the RHM2366B; neither specification tells you when your butter has softened, so check it between short intervals.
Is a flatbed combination microwave useful for baking?
A flatbed is useful if removing the turntable helps accommodate the dishes you use. Panasonic UK & Ireland lists a turntable-free cavity for the NN-DF38PBBPQ and a larger, two-level flatbed format for the NN-CF87LBBPQ. Measure your own cookware against the exact model's usable space.
What should I check before buying a built-in combi?
Check the exact model's required cabinet niche, ventilation and electrical installation instructions before ordering. Bosch GB specifies its built-in CMA583MS0B appliance dimensions as 454 × 594 × 570 mm, but appliance dimensions alone do not establish cabinet compatibility.
Do connected features help when softening butter?
They are not necessary for manually setting short, gentle heating intervals. If connected cooking matters for other tasks, check the requirements of the exact model: Samsung states that relevant connected features on its MC32DB7746KCE3 require Wi-Fi and a Samsung account.
