Even for cooks who enjoy preparing meat in their NuWave, durability is a serious issue. One glowing, four-star review on Amazon begins with the words, "This is my second NuWave..." Many other NuWave enthusiasts report that their device failed within a year of purchase. The warranty is very limited and replacement parts are so expensive that most users opt to replace instead of repairing. Considering that a NuWave oven costs between $99 and $170, the short life expectancy of the oven seems quite daunting.

Another concern with the NuWave is the instruction manual. Many reviewers felt it was confusing and poorly worded. Also, recipe instructions and times often had to be modified in order to produce good results.

The NuWave is by no means the only choice for those wanting a counter top convection oven. With similar claims and equally enthusiastic reviewers, the Aroma Housewares AST-900E AeroMatic Convection Oven ($89.99), the Sunpentown Super Turbo Oven ($68), and the Deni Glass Convection Oven ($79) all offer efficient, healthy cooking at a reasonable price.
