Very well thought out design

I've had my Bosch kitchen machine for almost a year now and I'm extremely happy with it. The swing arm motor design at the top is so clever. Allowing for any accessory to be attached simply by rotating the arm. There are excellent safety features, requiring everything to be closed, screwed down and properly attached before the motor will engage. There are also some simple but very useful design touches like the retractable power chord, the suction cup feet and the storage bag that fits inside the main bowl. But best of all are the results. Every cake I've baked has been delicious, meringues perfect and pizza dough fit for any Italian restaurant. It is a joy to use and I'm sure it'll last many, many years.

What’s not to like

Had this machine 3 months. My main use is kneading bread; I suffer dust allergy so using a machine reduces exposure to flour dust. I was nervous about a machine kneading and the Internet is littered with stand-mixer reviews - heavily criticising for lack of power or serious wobble - Fear not the Optimum takes it in its stride; fantastic dough consistency, I cannot praise the build quality enough. If you are undecided, take it from me you will not be disappointed.

Compact and versatile

Ok so I've only had this a couple of weeks but I have used it every day and I've used all the attachments that came with it apart from the mincer. I can now make the best coffee and walnut cake I have ever eaten. I like that this machine is compact so I can leave it out in my small kitchen. I like that it comes with so many attachments. I like how you can grate nuts (or carrots etc) straight into the mixing bowl directly into your cake mix. The attachments are a bit plasticy but do the job nicely, the main unit is very solid and the mixing bowl is heavy solid stainless steel. Now experimenting with bread making for the first time and it's a pleasure to watch it kneading dough. very happy with purchase

It works very well, does great cakes & looks good

I am an enthusiastic amateur when it comes to baking and I had been looking for a good robust machine that is not over the top for my level, yet powerful and versatile, appealing to the eye and reasonably priced. The MUM range and this model in particular does it for me. It is a lovely machine. easy to use, easy to clean and very effective. Lots of accessories which work nicely. My favorite one is actually the juicer because I have had so many of those and was never satisfied with them: Bosch just got it right: good size, easy to install, not bulky etc...and I think this goes across the whole range of accessories. I love my MUM5 and I love seeing it everyday waiting for the weekend baking bonanza!! well done to Bosch. I would also add that I had to contact customer service for a small issue on another device and they were the nicest and the most helpful. My problem got resolved in no time.

Love it !!

Just bought this and it does everything I want. Very pleased
