Skip if you need a freestanding range with a rear control panel, the slide-in design requires cabinet flanking on both sides. Also skip if 5 reviews is too small a sample for your comfort level, even at a 4.4-star average.

Overview
At 6.1 cu ft, the COS-GRC366KB has one of the more spacious oven cavities you will find in a 36-inch gas range under $2,100. That space translates to room for a full roasting pan alongside a side dish, or three full racks of baking sheets running simultaneously with the 3 included racks. For households that cook large meals or bake in volume, the oven capacity is a genuine differentiator.
Six sealed burners on a 35.9-inch surface give you good spacing between cooking positions. Sealed burners at this price range are standard practice, they contain spills, clean up faster than open burners, and maintain a clean aesthetic. The polished finish on the COSMO looks sharp as a slide-in install flanked by cabinetry. At 225 pounds, installation takes two people or a professional, but it is not unusually heavy for a 36-inch gas range.
Five reviews at 4.4 stars is a small but encouraging signal. Early buyers appear to be satisfied, and a 4.4 average with no obvious low-score outliers is a reasonable starting point. The 120-volt listing likely refers to the ignition and clock, the main gas burners do not run on electricity. At $2,047.99, this range offers a compelling oven-to-dollar ratio in the 36-inch gas category.

Performance notes
Six sealed burners across 35.9 inches give you comfortable spacing for running large cookware without crowding. The 6.1 cu ft oven with 3 racks at 29.6 x 35.9 x 37.1 inches (D x W x H) is a well-proportioned cavity for the footprint. Knob controls handle ignition and heat adjustment directly, straightforward and reliable. Gas fuel means you need an active gas line; no electric conversion is available on this model. The 120-volt connection powers auxiliary features like the igniter and interior light. Polished finish shows fingerprints more than brushed stainless but cleans up quickly.
What buyers say
Early feedback from 5 buyers averages 4.4 stars, which is a positive start for a relatively new listing. The sample is small enough that a few additional reviews could shift the average noticeably in either direction, so check current ratings before purchasing. At this price point, the positive early signal is meaningful but should not be treated as a settled verdict.
Is the COSMO COS-GRC366KB a true slide-in range or freestanding?
It is listed as a slide-in range, meaning it is designed to fit between cabinets with unfinished sides and front-facing controls. The mounting type is listed as freestanding, which likely refers to the structural footprint rather than the installation style. Confirm with the seller whether the sides are finished if you plan to leave it exposed on one side.
Why is 120 volts listed if this is a gas range?
Gas ranges still require a standard electrical connection, typically 120 volts, to power the electronic ignition, interior oven light, digital clock or display, and convection fan if equipped. The gas line handles all the actual heating; the 120V outlet just powers the electronic components.
How does the 6.1 cu ft oven compare to other 36-inch gas ranges?
A 6.1 cu ft oven is on the larger end for a 36-inch gas range. Many competitors in this class offer between 5.0 and 5.8 cu ft. The extra capacity is particularly useful for holiday meals, large roasts, or households that regularly bake in batches. If oven size is your top priority in a 36-inch range, this model is a strong candidate to compare.
