I was hesitant about purchasing this product, as I have the 6qt Ninja One Lid.  Glad I took the plunge.  Smaller foot print, much lighter weight and I think the square pan gives you more cooking service.  I can fit 4 good size burgers in it, compared to only 3 in the round pan.  I don't pressure cook that much, so I'm not really missing my One Lid.  What ever the coating is on the pan & crisping. tray is smooth as silk.  Clean up has been a breeze.  Haven't had it a week yet, but I've been using it every day. Again LOVE THIS MACHINE!!
