These things are junk. the clear dome and the extender dome cracks after several uses and makes them worthless.
Hyped up piece of junk if you ask me. When they work they work great but once the dome is cracked it really makes the whole thing useless since the idea is a area enclosed to maintain the air swirl and heat around the food. I would never purchase another one and make sue it is buyer beware.
Got one for my daughter and she is having the same issues with hers. So that makes 2 NuWave ovens that are not living up to expectations.
