Some common complaints concerning the NuWave oven include defective power domes, deceptive pricing, overcharging for the product and poor customer service. The Better Business Bureau conducted an investigation on the product in early 2014 and found the most common complaints are about substantial shipping and processing fees.
The NuWave Oven has a rating of 2.3 out of 5 stars on PissedConsumer.com, as of June 2015. Its lowest ratings come from the product's quality and customer service, although it typically receives better ratings for design and ease-of-use. The Better Business Bureau began its investigation after receiving nearly 1,300 product complaints in three years. Its investigation resulted in an "F" rating. In response, NuWave, LLC revised some of its shipping costs in late 2014 and initiated a MyComplaints program for better complaint response.
