I have a black cover and a gold cover. Have you guys tried the new app version with the full temperature dial? It also charges up for 3 seconds before each hit. I think it works better. When it gets warm, i just hit it without waiting the 3 seconds, works well. I love that they keep it evolving rather than make a FF3 with the new firmware. Pax comes out with a new one pretty often. I lost my respect for Pax when they wouldnt honor the 10 year warranty after even 1-2 months. So i decided, forget Pax products. Its still tasty but i can find cheaper conduction ovens So you can change the temp on the FF2 unit as well? Did not know that! With the new version i keep it at like 405 F. Used to always use the 420 F high setting Seems really hot but its only exposed to that temp for a few seconds. Would be different if it was a Crafty set to 420 or an Air.
