Who knows why? Maybe the unit was faulty and the factory fixed them all. At least that's better than ones people returned in my opinion.
They both appear to hold 12 cups so I'd probably get the one basket type unless you like to deep fry two different things at once which probably isn't a great idea anyways
Hey don't get upset I'm just making a suggestion dude. In my opinion not everything cooks at the same temperature, and I don't usually want the flavors of the different foods to mix in the fryers unless you like everything tasting like fish or onion rings. I'd rather be able to do one full basket of something instead of 2 half batches
