Skip if
Buyers who need a freestanding range, the slide-in design requires fitting between cabinets and the front controls are exposed, which creates a gap if removed. Also skip if you need more than 5 reviews for purchasing confidence.

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
Slide-in ranges differ from freestanding models in that they sit flush with countertops and lack finished sides, creating a more built-in look. The COS-GRC305KTD brings that aesthetic at $1,553 with gas cooking, sealed burners, and a 6.1 cu ft oven, one of the larger oven capacities in the 30-inch range segment.
The hybrid knob-and-touch control system places gas burner controls on physical knobs while offering touch-based input for oven functions. This split makes practical sense: physical knobs for rapid burner adjustment, touch controls for setting precise oven temperatures and modes. The stainless steel finish is standard for the category.
At 26.8 x 29.9 x 35.5 inches and 227 lb the unit is solidly built for a 30-inch gas range. With 5 ratings averaging 4.7 stars, early buyers report positive experiences. The limited review count is the main uncertainty, 5 reviews is not enough to assess long-term durability definitively.

Performance notes
Sealed gas burners on a 30-inch cooktop provide responsive heat control for everyday cooking. The 6.1 cu ft oven accommodates large roasting pans and full sheet pans for batch baking. Slide-in installation at 29.9 inches wide fits standard 30-inch openings between kitchen cabinets. At 35.5 inches tall the range surface aligns with standard 36-inch countertop height when seated in the cabinet opening. The stainless steel finish resists discoloration from heat.
What buyers say
A 4.7-star average from 5 buyers is a genuinely positive early indicator, with no negative reviews in the current data. Buyers appear satisfied with the product as described. However, 5 reviews represents a very small sample, and buyers making a $1,553 decision should track whether future reviews maintain this pattern or reveal issues not yet visible.
What is the difference between a slide-in and freestanding range?
A slide-in range is designed to fit between two base cabinets and sit flush with the countertop, giving a built-in look. The sides are unfinished and the controls are at the front. A freestanding range has finished sides and a backsplash with rear controls, and can stand alone or fit between cabinets.
Does slide-in installation require professional help?
Slide-in gas ranges require a licensed gas technician for the gas line connection regardless. The physical placement between cabinets is straightforward, but the slide-in fit must be precise, confirm the opening width is correct for the 29.9-inch body before delivery.
How does the knob and touch control system work?
On the COS-GRC305KTD the gas burner controls operate via physical knobs for immediate tactile adjustment of flame level. Oven functions, temperature setting, mode selection, timers, are managed through touch controls on the front panel. This means you are not dependent on touch sensitivity when adjusting burners at speed.
