This brand mainly has three series: diamond, titanium gold and ordinary. Now it seems that these three series have been subdivided. Some time ago, I heard from a customer service that the order from high-end to ordinary is: perfect diamond, perfect titanium gold, titanium gold, diamond strengthening and sapphire.

Mainly according to the thickness of the bottom of the pot to distinguish.

The bottom of the perfect diamond series is 10MM thick and has the longest warranty, that is, 25 years.
