Overview
At $1,889.99, the COS-30EDWC occupies the mid-range between budget Samsung options around $1,099 and premium ZLINE or GE units above $3,000. The 4,800W power rating is reasonable for an electric wall oven at this size, and convection in both cavities allows fan-circulated heat for more even baking and roasting.
The 30-inch width is a standard fit for most wall oven cutouts, and the stainless steel finish is a safe, versatile choice. Dimensions of 23.5 x 29.87 x 51.18 inches and a 236.5 lb weight fall in the typical range for built-in double wall ovens. It runs on a standard 240V circuit.
With 37 reviews at 4.0 stars, this is one of the better-validated options in the double wall category on this site. A 4.0 average signals general satisfaction but also that some buyers encountered issues, which is expected at this price point.
