What to know before buying

Listing details to confirm

Listing details are contradictory or inconsistent: the main listing and feature text give 20 litres and exterior dimensions of 32.5D x 44W x 25.8H centimetres, while manufacturer material also states 23L and gives different microwave and cavity dimensions. The main listing specifies a 25.5 cm turntable, but other material gives a 255 mm turntable, which is equivalent. Confirm the exact capacity and measurements for the selected listing, especially if fitting a particular dish or shelf.

Frequently asked questions

Is this microwave suitable for a small kitchen?

The listed exterior dimensions are 32.5D x 44W x 25.8H centimetres, and the 20-litre capacity is positioned for compact spaces. Check the conflicting dimensions in the listing before choosing a shelf or fitting location.

Does it have automatic cooking programmes?

The main listing describes manual controls and five power levels. Separate manufacturer material mentions six presets, so whether presets apply to this exact model is unclear. Confirm the selected listing if presets are important.

Can it defrost food by weight or time?

The feature information describes defrost by weight and time. The listing also identifies defrosting as a cooking programme.

Will a 9-inch pizza fit?

The title says it is suitable for a 9-inch pizza, and the listed turntable diameter is 25.5 Centimetres. Check the dish or pizza dimensions, since the stated capacity and interior measurements conflict elsewhere in the listing.
