I bought a nuwave and if I had it to do over, I would just get a large countertop convection.
I wanted to try the infrared technology but it is no better than convection plus you have to wash the whole thing after each use and a regular convection, you can just wipe out like a toaster oven.
Also if you cook something large, the top will be more cooked since the element is up top.....even though the air circulates around the item...still the heat source is right on top of a whole chicken or turkey.
And if you want crispy steak w a more rare or med rare inside, nuwave won't do it unless the steak is really thick (mine are 1").
There should be some great deals during the holiday season. Shop around for the best size/price.
