I purchased the 5.2L Opti Fry and my daughter quickly snaffled that up. So I purchased the 7.2L and it's HUGE.
Cooked 4 chicken schnitzel parmi's with chips in one go. If you go to Open Shop's face book page you can see a photo that I posted.
So convenient and a breeze to wash up.
I have separately purchased an accessory pack that has a rack, cake tin etc which allows me to cook heaps of things in the Opti Fry.
I highly recommend this product !
