With 900 Watts of power, this Kenwood mixer easily brings all of your ingredients together. The attachments spin in a Planetary Mixing Action, rotating as they move around the bowl to ensure sure not even a speck of flour is missed, for flawless results. For extra control, the pulse function helps you reach the exact consistency for your recipe. Thanks to the connection safety mechanism, the mixer won’t work if your attachment isn’t securely in place. There’s even a handy dough tool to help you create delicious breads and pastry.

So far so good...

So far have made some delicous cakes with my mixer. All functions work well. No issues with spillage or splashing over the edges as previous reviews have noted. Also looks great in kitchen, perfect size for a smaller space.

Not pleased..

Within a short time the bearings became loose so the hook travels up and down drastically. The first time of using the juicer; the gears stripped so then the liquidiser was impossible to use as well as the juicer. The food processor attachment works well. The silicon protection disc soon ripped allowing bread doe into the fixing hole. Not rigid enough for mixing bread doe and was soon quite noisy and inefficient. Previously I had three Kenwood Chefs all of which burnt out. I am now looking for a strong reliable machine.


Easy to use, does rhe job just as well as the more expensive mixers. Love it


After having a Kenwood chef for many (30+) years I was very disappointed with this mixer. Flour is thrown out even at low speeds, and the splashguard channels any escaping mixture towards the machine. Also the beater is not easy to release and the bowl has now come way from its base and a new bowl costs £40. I’ve only had it 2 years.

Kenwood food mixer

Not as good as expected .. the plastic lid for the bowl is very poor quality and the sugar and flour flies out past it even tho its properly put in place ... for the money - not the best ...

Great mixer

Delighted with this, my first food mixer. Does the job quietly and efficiently. So far I've only used it for bread dough and it's just great .. I was getting fed up with the kneading process and having sticky dough on my hands but this does the job cleanly, quicker and is now part of my routine making bread 2/3 times a week. Next weekend it's cake time.
