Futura Hard Anodized Tava

I asked my friend to get this tava and it was a huge mistake. Until now I have not figured out how to make it work without anything sticking, no matter how much oil is put on tava, from rotis, dosas to vegetable cutlets. I will stay away from Futura hard anodized tavas in future.
