Have compared with same sizes of other manufacturers that pot. In each pot, the same amount of water in, with the same temperature and comparatively measured the time until it boils. In the race was a quality series with the imprint "iitala" and yet a cheaper series with the imprint "Exclusive Line". Result is that Tefal heated fastest. The quality iitala even the slowest. Now what is to draw on knowledge? Firstly, I would say it is clear that the thicker bottom of iitala clearly more energy absorbs and therefore easy slower heated but also longer stores. But it also says that the Tefal must be quite good kontruiert. The improper processing would not conduct the heat properly. But why then only 4 stars? Because I did not like the rivets. The photos have been "accidentally" so added that this little detail reveals not so pretty. I find that in the purification of little advantage compared to a completely smooth inner surface as the iitala has. But otherwise seems to be no reason to complaint processing quality of Tefal series. The lids are Passignano and the bottoms of the pots are all planned. Conclusion: Good and decent Qaulität a cheaper series. Riveting the grip elements in otherwise good quality. Excellently suited for very rapid heating to induction. Therefore very good 4 stars.
