I've had a lot of grills in my life, most of them, besides the Weber pot/charcoal grills, have been average at best. Some, like the Charbroils, were just awful. The Signet 20 has plenty of usable grill area, the temperature control is excellent, and the thing heats up to over 550 degrees with just three burners. I've used it 6 times since I bought it and I am very satisfied.
The lower part of the base is plastic, so I hope that that prevents the lower rust-out that plagued my last grill. I think that this unit is an excellent buy, considering the sub-par company that is offered as competition. It compares favorably to the 3-burner Weber that costs $100 more.
