I recently purchased my NuWave Oven online. I have used the oven honestly about 8 times. About the 3rd time, a loud noise started coming from the vent like the sound of a fan about to shut off. My other issues are about the same as some other people’s reviews. The melting, the having to turn food over. The bottom of the NuWave is so HOT it caused the glue from my countertops to melt. I have to sit it on my cutting board. These details should be included in the advertisement. I am sending it back for a total refund.
