In Dec 2007 I purchased a Nu Wave Oven Pro.I use it once each day.
It is now May 29 and today I just received the second replacement dome because the first 2 domes developed large cracks, just from normal use. I complained to the seller who told me that the dome I received today was going to be heavier. Well it isnt heavier it is exactly the same as the last 2 domes, made of plastic!! I would never have purchased the oven if I knew that the dome is made of plastic.
It cannot endure high temperatures.
