I prefer the NuWave, I have had it for over 5 years. The NuWave has a longer lasting heater inside the powerhead. The Halo is more like a halogen lightbulb. I like the NuWave because it is not a heavy glass that also becomes very hot. I would not want my kids to use it. With the NuWave my kids can use the NuWave after school and I am not worried about them getting hurt or burnt. I found a NuWave oven facebook page that has a lot of people talking. Hope that helps
