It does what it promises, but it requires very good adjustment of the axis in order to minimally touch the flexible material of the mixer with the walls of the container

Good to use it but you don't completely eliminate the noise... otherwise, I found it at a good price and bought it. Generally, Kenwood accessories are inexplicably expensive. I had it on my list for 2 years until its price dropped.

It does what it promises, but it is a bit noisy under specific conditions, at least in a glass bowl. However, it completely eliminates the need to stop and scrape the walls with a spatula. Be careful to use it only with soft mixtures.
