Design and Build Quality
The Monument Mesa 415BZ features a distinctive large viewing window in the lid that sets it apart visually from the sea of stainless steel grills dominating the market. This aesthetic choice not only provides a unique look but also offers practical benefits in terms of being able to view your food without lifting the lid.
The grill cabinet and frame utilize a combination of powder-coated steel and stainless steel elements, striking a reasonable balance between durability and affordability. By viewing the overall weight alone, you probably guessed this is not constructed of heavy-duty materials like that of premium grills at higher price points.
Four plastic casters (two of which lock) provide mobility on most surfaces, though they perform better on smoother patio surfaces than on rougher terrain or grass. The control panel is clearly marked with larger knobs than many competitors, making adjustments easier.

Cooking Performance
Heat Output and Distribution
The four main stainless steel burners generate a combined 50,000 BTUs of heat across the primary cooking surface, providing substantial power for most grilling tasks. Heat distribution is generally good across the cooking surface, though some users report slightly cooler corners—a common issue with rectangular gas grills in this class.
The porcelain-coated cast iron grates offer excellent heat retention and produce impressive sear marks. They require proper maintenance to prevent rusting but represent a significant upgrade over the thinner grates found on budget models.
Temperature control is responsive, allowing for both high-heat searing and indirect cooking at lower temperatures. The built-in thermometer provides adequate accuracy for general grilling, though serious cooks might still prefer using a separate digital thermometer for precision.
Cooking Versatility
The 12,000 BTU side burner adds considerable versatility, allowing for preparation of sides, sauces, or other accompaniments while main dishes cook on the primary surface. The lidded design means this space can double as additional prep area when the burner isn’t in use—a thoughtful touch for those with limited counter space.
With 450 square inches of primary cooking space, the Mesa 415BZ can accommodate approximately 23 burger patties simultaneously (supposedly), making it suitable for medium to large gatherings. The additional warming rack provides space for toasting buns or keeping food warm while other items finish cooking.
Unique Features
The Monument Mesa 415BZ includes a few notable features that distinguish it from competitors:
- LED-Illuminated Control Knobs: LED lights illuminate the control panel, improving visibility during evening cooking sessions—a genuinely useful feature rather than mere aesthetic.
- Built-in Bottle Opener: A seemingly small addition that proves convenient during outdoor entertaining.
- Window Lid: The large window built into the lid provides both aesthetic differentiation and practical benefits in terms of heat retention.

Ease of Use and Maintenance
Assembly requires approximately 1-2 hours with basic tools, with instructions that are clearer than many competitors. The electronic ignition system reliably lights burners with a single push in most cases, though occasional issues have been reported after extended use.
The grease management system consists of a removable drip tray that slides out from the back of the grill, which works effectively but can be slightly awkward to access compared to front-accessing systems. The porcelain-coated cast iron grates require regular maintenance (oiling after cleaning) to maintain their non-stick properties and prevent rusting.

Value and Recommendation
The Monument Mesa 415BZ occupies an interesting position in the market, offering several features typically found on more expensive models while maintaining a mid-range price point. The grill represents solid value for consumers seeking an upgrade from entry-level models without venturing into premium price territory.
This grill is particularly well-suited for:
- Entertainers who frequently host medium to large gatherings
- Grillers who value cooking versatility with both direct and indirect methods
- Those who appreciate thoughtful design touches like tool storage and lighting
- Buyers seeking better build quality than budget models without premium pricing
- Users who prioritize searing performance and heat retention
Those seeking professional-grade construction or specialized cooking capabilities might need to look at higher-priced options. However, for everyday grilling needs with some additional versatility, the Mesa 415BZ delivers performance that compares favorably to many more expensive alternatives.
Conclusion of the Monument Mesa 415BZ Review
The Monument Mesa 415BZ strikes an effective balance between performance, features, and affordability. While it doesn’t quite match the construction quality or refined engineering of grills in the premium segment, it offers significant upgrades over entry-level models in terms of cooking capability, durability, and thoughtful design features.
The distinctive large viewing window, illuminated controls, and generous cooking capacity make this grill an attractive option for those seeking to elevate their outdoor cooking without breaking the bank.
