EXTERNAL CUSTOMER FEEDBACK
OUR PRODUCT ASSESSMENT
Imperial is the Broil King range we would look at for a more complete outdoor cooking setup. Cast-stainless cooking grids, substantial burners and available rotisserie equipment give it a strong foundation, while the larger dual-oven versions let you run different cooks side by side. The island packages add a coordinated work area, and QS models bring iQue controls. Those choices should earn their place in your kitchen. Decide how much grill you will use, then plan access, power and maintenance around the exact configuration.
Owners particularly appreciate the freedom of separate ovens on the larger Imperial models, whether that means cooking different foods or using only the smaller side for dinner. Even heat and rotisserie results also stand out in their accounts. There are practical reservations: one owner needed thermometer attention, another discussed lighting repairs, and another noticed uneven heat with time. These experiences point to a capable cooking platform whose supporting components still deserve a careful setup and a clear service plan.
The dual-oven configurations let you separate cooking tasks instead of committing the entire grill to one temperature. That is useful when a roast needs gentler cooking while another dish needs direct heat. This advantage belongs to the dual-oven models, not every Imperial in the family.
Cast-stainless grids and the burner system are the reasons to consider Imperial before the decorative details. Equipped models add a rear burner and rotisserie for another cooking method. Check what comes with the chosen built-in head, because an island image may show equipment sold as part of a larger package.
The island versions combine the grill with storage and a countertop. That can simplify the visual and practical planning of a cooking area. QS versions add connected control; conventional S configurations remain an option if you prefer a familiar routine without that additional layer.
Measure the grill, lid movement, work surfaces and service access together. Island and built-in configurations need different planning. Confirm fuel and electrical connections before delivery, and make sure the route into the yard can accommodate the package you choose.
Clean the cooking system and grease areas, and check the care instructions for the grids and exterior finish. Lighting, temperature instruments and connected controls add useful functions but also serviceable components. Keep their coverage distinct from the main grill structure when comparing warranties.
Imperial is easiest to justify when you will use the additional cooking capability or the coordinated island regularly. A smaller built-in may be a better purchase than the largest dual-oven island if most meals are for two. Compare the cooking features, cabinet contents and installation total rather than judging value by the number of burners alone.
