Consider the product features of the GR-4, which is marketed as a 4-in-1 that can be used as a griddle, open grill, contact grill or panini press.
Note the product specifications for the GR-4, which measures 16 and 2/3 inches by 9 and 2/3 inches by 12 and 2/3 inches. It offers a three-year limited warranty and weighs 14 pounds.
Compare the product features of the GR-4N, which is marketed as a 5-in-1 appliance that can be used as a panini press, contact grill, full grill, half grill and half griddle and a full griddle.
Compare the product specifications of the GR-4N, which measures 13.5 inches by 11.5 inches by 7.12 inches in size. The total weight is 11 pounds, and the unit has a three-year limited warranty.
Note the similarities of the GR-4 and GR-4N, both of which have a brushed stainless steel exterior, floating cover that adjusts based on food thickness, integrated drip tray, adjustable temperature controls, panini-style handle, and removable nonstick cooking plates. The included scraper, drip tray and plates are dishwasher safe for both units.
Consider the fact that the primary difference between the two grills is the half-grill, half-griddle feature on the GR-4N. The GR-4 unit does not have this feature. There is a slight difference in weight -- the GR-4 griddle weighs around three pounds more than the GR-4N.
Consider the price point of both units. The GR-4N unit retails for approximately $91, and the GR-4 unit retails for approximately $95.
