900w microwave ovens strike a happy balance between energy efficiency and power. Opt for a standalone microwave, add in a grill for browning or go for a versatile fan option. These appliances have the capability to cook food swiftly, so defrosting and baking are hassle-free and speedy. High-tech options include inverter technology to provide even penetration, while automatic weighing removes the guesswork from timing. Built-in models can coordinate with your oven and hob – look to slimline designs for compact spaces.
