198 owner reviews, more than most models here
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 grills, grill parts and burners, smokers and smoking gear, grill tools, outdoor griddles, outdoor kitchen appliances and grill covers 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
The Onlyfire GS309 packs three propane burners into a 14 x 23.6 inch footprint that weighs 47 pounds. The 315 square inch primary cooking surface is enough for a dozen burgers or a few chicken breasts at a time, but it is not designed for large-scale entertaining.
Stainless steel construction keeps the weight manageable while providing decent resistance to outdoor conditions. The 4.3-star average across 198 reviews is a solid result, representing a real-world buyer consensus rather than a handful of early purchases. At $219.99, this sits at the lower-to-mid range for three-burner freestanding grills.
The small depth of 14.5 inches makes this one of the more space-efficient designs in its class. For people with a small balcony, a compact deck, or a tailgating setup, the size-to-price ratio is one of its main advantages.

Performance notes
Three propane burners heat a 315 square inch stainless steel cooking surface. The unit measures 14 x 23.6 x 14.5 inches and weighs 47 pounds. No BTU figure is provided by the manufacturer. The small depth and compact width are well suited to constrained outdoor spaces. Stainless construction on the exterior and grates reduces maintenance burden.

Frequently asked questions
Can the Onlyfire GS309 fit on a small apartment balcony?
At 14 inches wide and 23.6 inches deep, the GS309 is one of the more compact freestanding grills available. It can fit on most standard balconies. Before putting any gas grill on a balcony, check your building's rules and local fire codes, as many buildings restrict or prohibit gas grill use on balconies.
How much can you cook at once on the GS309?
The 315 square inch surface fits roughly eight to twelve burgers depending on size, or four to six bone-in chicken pieces. It is practical for two to four people. For larger groups, multiple batches will be needed. The three-burner setup helps manage indirect heat for thicker cuts by keeping one burner off while using the others.
