2 owner reviews, fewer 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
This four-burner version of the Thermora A-TR-GG shares the same cast iron and stainless steel construction as the three-burner model but scales up to 645 square inches of cooking area, making it one of the roomier options in the under-$600 propane segment. Four burners across that surface gives good zone flexibility for indirect cooks alongside direct grilling.
The footprint matches the three-burner sibling at 22.1 by 46.1 by 56.5 inches, meaning the extra cooking area comes from a wider or deeper grate arrangement rather than a larger cabinet. At $566.99, it sits squarely in the mid-range where competition from more established brands is strong.
With only two reviews, there is almost no data to draw on for reliability or long-term satisfaction. Both reviewers gave five stars, which is a positive start, but no meaningful conclusions can be drawn from two responses. Buyers should weigh the limited feedback accordingly and consider verifying warranty and parts support before purchasing.

Performance notes
Fuel is propane. Four burners cover 645 square inches of cooking area, which supports feeding eight to ten people in a single session. Cast iron grates build seasoning and hold heat longer than porcelain alternatives. The stainless steel housing resists surface corrosion. BTU output is not published. The tall 56.5-inch total height keeps the cooking surface at a comfortable working level. Dimensions are 22.1 by 46.1 inches at the base.
What buyers say
Two reviewers have rated this grill 5 out of 5 stars. That is an encouraging start but statistically insignificant. No negative feedback exists at this point, but the absence of critical reviews should not be interpreted as an absence of potential issues. More owner feedback over time will clarify the real-world performance picture.

Frequently asked questions
How does this model differ from the three-burner Thermora A-TR-GG?
The main differences are one additional burner and roughly 92 more square inches of cooking area, going from 553 to 645 square inches. The price jumps from $329.99 to $566.99. Both models share the same cast iron and stainless steel build and the same tall cabinet dimensions. The four-burner version is better suited for larger groups or more complex multi-zone cooks.
Is 645 square inches enough for large gatherings?
645 square inches comfortably fits around 30 to 36 standard burger patties at once, which is enough for most backyard parties of 10 to 12 people. If you regularly cook for larger crowds, you would want an even larger cooking surface or a second grill running alongside.
Should the two 5-star reviews affect my purchase decision?
Two reviews are not enough to form a reliable picture of how a grill performs over months of use. The early feedback is positive, but questions about igniter durability, grate longevity, and burner performance over time are still unanswered. If you need more confidence, waiting for more reviews to accumulate or choosing a model with a larger review base is a reasonable approach.
