First, you need patience with the Cobb. The first barbecue attempts are quite doomed. The Cobb is very demanding as far as the fuel. With cheap coal briquettes or this simply does not come up to speed and will remain too cold for a good barbecue. With the right carbon (Weber Steakhouse've taken, although very expensive, but you need not so much), he grills really good. One should let Allerding by heat with the lid closed about 5-10 minutes before hanging up the Grill Good rust. When you consider these things and possibly also the cheap coal specifically used (eg for low and slow to smoken, Pulled Pork, Ribs, ...) is the super grill for up to 4 persons (ideal for 2).
As for the accessories: The roast rust is very good and worth. The Griddel is a waste of money since the meat stewing too much in its own juice (maybe instead use the roast rust alone or on the use of the Sear Grate by Weber Cobb.)
Because of the still long for a barbecue learning phase and the admittedly very high price, there are "only" 4 stars. When you first mastered him and does not interfere with the price it would be 5 star.
Supplement 07 September 2013: have now bought a Sear Grate by Weber to Cobb. At last a really good BBQ for 2 people is possible. No ifs and buts. So who wants to be happy right grilling directly on the Cobb should buy the Sear Grate it. Fits made of the size as for the Cobb.
