Got my NuWave induction system on line. It came with two Nuwave induction systems, two fry pans and some other pans. Induction cook tops work with any pan you can you can stick a magnet to. So, they will NOT work with aluminum pans or some stainless pans. The cook top gets hot from the pan so will not smoke or catch fire when grease touches it. Nice for an RV. I keep my second NeWave in my TT and cook on the picnic table with it (need a bigger kitchen in my TT). So, cast iron pans work awesome on an induction cook top.
I just got a pressure cooker that works great on my NuWave cook top.
