Broil King grills are known for their quality and durability, and the Regal 590 IR is no exception. Customers have reported that the grill is well-made and has a beautiful design, but it can be difficult to maintain due to its heavy construction and rust-resistant materials. Additionally, some customers have experienced issues with the cookbox and handle collapsing after a few hours of use. Despite these issues, customers have been satisfied with their purchase and are looking forward to their next barbecue.
