The Cosmo COS-EPGR366-BK is a wide 36-inch slide-in range with a 6.0 cu ft oven and six sealed burners in a black stainless finish, priced at $2,550. With only one review sitting at 3 stars, buyer confidence cannot be established yet.
Buyers upgrading a larger kitchen who want a 36-inch slide-in profile and black stainless aesthetics, and who are comfortable being early adopters of a lightly reviewed product.

Shoppers who need proven reliability data should look elsewhere, one 3-star review is not enough to validate a $2,550 appliance. Also skip if a standard 30-inch range will cover your cooking needs.

The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other kitchen ranges, cooktops, wall ovens, range hoods and microwaves we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
At 35.87 inches wide and 27.91 x 35.87 x 36.93 inches overall, the COS-EPGR366-BK is built for kitchens that can accommodate a 36-inch cutout. The 6.0 cu ft oven is notably large, among the roomiest in this category, and the six sealed burners on the cooktop give flexibility for multi-pot cooking. Slide-in installation tucks the unit flush between countertops for a cleaner look than freestanding designs. Controls are knob-based, and the black stainless steel finish suits modern or matte-forward kitchen styles.
At $2,549.99, this is a premium-tier price tag for a Cosmo product. The 235-pound weight signals a substantial build, and the 120V electrical connection is worth confirming against your kitchen's hookup before purchasing. Heating method is listed as sealed burner, which generally means a gas cooktop with contained flame wells for easier cleaning.
The solitary 3-star review on record is a significant caution flag at this price. Early production models can carry quality inconsistencies that only surface in real-world use, and there is not yet enough owner data to assess whether this range delivers reliably over time.
Pros
Generous 6.0 cu ft oven, well above average for slide-in ranges
Six sealed burners on a 36-inch cooktop for serious multi-burner cooking
Slide-in design for a built-in, flush countertop appearance
Black stainless steel finish is a distinctive aesthetic choice
Cons
Only one published review at 3 stars, far too little feedback to trust at $2,550
Premium price for a brand that lacks the owner-verification trail of major appliance makers
Fuel type not explicitly listed, verify gas vs. electric before ordering
235-pound weight makes delivery and installation logistics demanding

Performance notes
Six sealed burners on a 36-inch cooktop allow simultaneous use of large pots and pans without crowding. The 6.0 cu ft oven is large enough to handle a full-size turkey, multiple sheet pans at once, or large roasting setups. Two oven racks are included. Knob controls handle all cooktop and oven functions directly. The slide-in installation format requires an existing 36-inch range cutout, it is not a drop-in replacement for standard 30-inch openings.
What buyers say
With only one rating on record at 3 out of 5 stars, there is almost no buyer consensus available. A single midpoint rating suggests neither enthusiasm nor disaster, but it is statistically meaningless. Prospective buyers should treat this as a largely unverified product and weigh that against the $2,550 price.
The listing identifies sealed burners as the heating method and notes 120V voltage, but the fuel type field is not explicitly populated. Sealed burners most commonly refer to gas cooktops. Confirm with the seller before purchasing to ensure it matches your kitchen's gas or electric hookup.
Will this fit a standard 30-inch range space?
No. The COS-EPGR366-BK is 35.87 inches wide and requires a 36-inch range cutout. It will not fit a standard 30-inch opening without cabinet modification.
How does the slide-in design differ from freestanding?
A slide-in range has no finished side panels and is designed to be installed between base cabinets, creating a flush, built-in appearance. Freestanding ranges have finished sides and can stand alone or between cabinets. The slide-in profile here means the cooktop overhangs the counter slightly to eliminate gaps at the sides.
