I bought this fan with a reward Balance a few days ago. 
Honestly, I did not expect that it is good. But, my thoughts was a 100% wrong. That fan was perfect.
Because I can cook with no oil and this fan preserve heating for a long time even though I turn off induction, so that food has still warm . And bottom color is black so I do not need to worry to clean after use it. 
I will recommend it  to my friends .
Absolutely!!!!!!
