A joy to use The Bosch OptiMUM MUM9GT4S00 Stand Mixer makes mixing ingredients a piece of cake. It has an extra-large 5.5 litre mixing bowl covered by a lid to make sure that everything you put in stays there. You can take the guesswork out of mixing by selecting one of the automatic programs like whipped cream or egg whites. The 3D PlanetaryMixing technology means that no part of the bowl will be left unmixed. You can even pre-set a running time for optimal, repeatable results. A joy to look at The OptiMUM is a premium mixer and it looks the part. It's been designed to look great in any kitchen and last for a long time. Its stainless-steel surface is easy to clean and durable. The 1.2 metre cable retracts automatically into the body to keep it out of sight.
