User reviews on IntelliReview laud George Foreman grills, a brand which generally refers to five categories of contact, open, sandwich press and indoor/outdoor grills, for being reliable. The brand's GGR50 Indoor/Outdoor Electric Grill, for example, has a rating of 4.5 stars out of 5 from 808 reviews.
George Foreman grills have a large, easily assembled cooking surface that is convenient to use indoors or outdoors. The only noted disadvantage is that the drip pan is relatively small for the size of the grill, requiring emptying several times when cooking large quantities.
The George Foreman press-style grills, models GRP99 and 4, are also reviewed well in the grill comparison by IntelliReview. Each have a rating of four out of five stars from hundreds of reviews. Both models feature a patented George Tough Triple non-stick coating that is noted as significantly more durable than standard types. The removable grill plates of the GRP99 model make thorough immersion cleaning simple.
ConsumerSearch suggests that there are better brands of contact, open and combination grill/sandwich press models than the George Foreman line. Although the GGR50B was lauded as the best indoor/outdoor electric grill, two models from Cuisinart, the GR-4N and GR-1, and one from Sanyo, the HPS-SG3, topped the George Foreman models. The GR-4N, which doubles as a contact electric grill and griddle, is rated well by ConsumerSearch for its versatility and removable, dishwasher-safe grilling plates.
