Product review (4 stars): Edited upon further usage, rating it higher now
At first I had some problems using it, as some of what seeemed to be genuine stainless steel didn't work on it and gave error code about inappropriate cookware, but... that could be because they are old and they may be flawed (though look and seem/claim to be stainless) -- I'll have to check the magnet factor (which I misplaced to this day during opening the box it came it!) --  Then, on usage with one of the 2 pans that DID allow cooking, I first got error code but on several attempts I came to realize that it was because the pan had gone over the circle border of cooking area during usage, and error released when pan placement adjusted. Now I can use it routinely for cooking and taking care to not stir in any way that would move the pan across the border area. The only thing I don't like is that there's no timer, but I can handle keeping good attention to what's going on if there is extended simmering. That is required.
