I’ve got a Cobb. I love it for going camping, can do so much with it. Treat it like a small portable charcoal oven though – roasts, casseroles, curry/chili/stew good if you get the deep dish frying pan thing. Plus you can steam using the moat, and use it for smoking meat and fish etc.
For actual UK style BBQing (ie get it hot and slap a ton of burgers and sausages on it) I find it a bit lacking, can get by for one or two people but not as good as an actual BBQ due to relatively small cooking area (the charcoal/fuel brick is held in the centre so direct heat on the outskirts of the grill not so hot).
I’ll always stick with the Cobb, nothing better than putting it on with a handfull of charcoal and coming back hours later after a days riding to a meal like it was out of a slow cooker only better cause it’s outdoors!
