Functions reasonably well but a little bit inconsistent with temperature control from day to day. This requires a bit more supervision during cooking, aided by glass lids on the saucepans. The English grammar in the instruction manual is really bad. Also the explanation of how to operate the button that toggles between the inner plate and full diameter heating is simply not there. Instead there is a repetition of an earlier instruction. I figured out that the relevant button simply toggles between full diameter and inner heaters by pressing it when the relevant element has been selected and then pressing it again when wishing to go back to the inner heating element. The wattages of each element are clearly shown in the instruction manual and that is very useful information to me. The end of cooking beeper is set appropriately and is not intrusive.
