This is my third robot Kenwood. The first with a capacity of 4,5l 600W lasted over 10 years. The second 6.7L, 12, 800W power I had to change it because I had used the rod of my trouble and hook inside the robot and making noise, I think due to his age. With the acquisition of new Kenwood KMM770 is a power of 1200W is a pleasure to make bread and other preparation, and it is much less noisy and above the price offered by Amazon is that I did not hesitate the purchased and fast delivery two days rather than planned and very well packaged. I recommend it to anyone who wants to equip.
