Have these pans items, bought from headless action herraus after I had seen the advertisement. Conclusion: On electric stove (ceramic) significantly worse than for example the Teflon pans of Lild & Co, as the heat absorption and the temperature / time are not competitive.. The heating lasts too long, the temperature is not maintained. The pans are simply too thin and the soil arching. Fried without fat test was a failure, the egg went to the edge and took ages, it was stuck and became scrambled.
On gas (I have a kind of wok burner, on the balcony, my summer kitchen) the pans are against top, especially as regards the adherence. Since you can work really well with!
I will keep the parts, return of used pans I find assi. For 40 Euro 3 pans because I whistle it, if that should be over, I'll throw it away and buy brand and 5 stars :)
