Panasonic NN-E28JBMBPQ

The NN-E28JBMBPQ is the choice when space, not capacity, is the constraint. Panasonic lists a compact 20-litre cavity, 800W output, five power levels and nine auto programmes for everyday jobs like jacket potatoes and chilled meals, with an indicative price of around £90 (RRP about £100). It sits above the cheaper Russell Hobbs below largely on brand pedigree — Panasonic's reputation for reliable, well-built microwaves — rather than on features, which are comparable. The trade-off is capacity: at 20 litres it will not swallow the largest plates or dishes, so if you need room, step up to one of the 23-litre models. Pay the small premium over the budget pick if brand reliability matters to you.
