The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.
Overview
The COS-RES304SS is a 29.88-inch-wide slide-in that fits the standard 30-inch cutout and sits at a manageable 36.18 inches tall. Its 4.8 cu ft oven uses radiant heating across 4 burners, running on 240 volts. Two oven racks are included, and at 156.5 lbs the unit is substantial without being unusually heavy for its class.
At $1,343.99, COSMO positions this slide-in between budget freestanding ranges and premium brands. Radiant heating is a reliable technology for even baking, and the knob controls keep operation straightforward. The stainless steel finish is a practical choice that works with most kitchen palettes.
The absence of any buyer ratings or purchase history is the honest limitation here. The specs are solid on paper, but there is no community data on long-term reliability, burner output, or oven calibration accuracy. Buyers are essentially early adopters at this price level.

Performance notes
The 4.8 cu ft oven with radiant heating is sized for everyday cooking and occasional large-batch baking. The 29.88-inch width fits a standard 30-inch opening cleanly. Four burners cover a typical household's simultaneous cooking needs. At 240 volts, the range draws full residential electric power for proper output. Knob controls mean direct, analog adjustment with no touchscreen lag. Two included racks allow multi-rack baking without an extra accessory purchase.
What buyers say
There are no buyer reviews for this product at this time, so there is no community sentiment to report. The lack of purchase history means prospective buyers cannot rely on crowd-sourced quality signals and should weigh that absence carefully before committing at this price.
Does the COSMO COS-RES304SS require a 240-volt outlet?
Yes, this range operates on 240 volts, which is standard for full-size electric ranges in North America. If your kitchen currently has a 120-volt outlet, you will need an electrician to upgrade the circuit before installation.
What type of oven heating does the COS-RES304SS use?
The oven uses radiant heating, which relies on electric heating elements to cook food. Radiant heat is well-suited to baking and roasting and is a common choice in mid-range electric ranges.
Is this a freestanding or slide-in range?
This is a slide-in range, designed to fit flush between cabinets for a more integrated look compared to freestanding models. The 29.88-inch width fits a standard 30-inch kitchen cutout.
