Initially, I was still very skeptical about whether the cup actually prevents overcooking milk. It works, as based in the article description, milk and milk sauce cook no longer and the MW clean. After some time of usage I am sorry to see that the material is extremely susceptible to scratching, stir for a few times with a whisk, the cup already looks very ugly. On the whole, the material is very soft, really a shame because for functional reasons a practical part.
