The first time I noticed that it has taken when searing (in this case of rolls) very long to tan arose. Compared to cheaper roasters such as a coffee company that is initially somewhat surprising.
The floor of my roaster is absolutely flat and and during Schmorphase nothing wobbled or vibrates (I use an induction cooker of Siemens). The result can certainly be satisfied. However, I ask myself whether the investment pays off in comparison to a cheaper pot. With a cheaper pot aluminum-based I came to delicious results (but with my old non-induction cooker).
It should be noted that the influence of the pot on the food you are better assess with a pot on enamel / cast iron base materials so that are in the cooking area for a long time in use. With aluminum I'm not so sure.
