We bought one last year, and I honestly wasn't sure if it would live up to the hype or not. A year later, and it is our main cooking source and pretty much our only outdoor cooking source. We use it all the time, it set up and breaks down easily and quickly. I leave the burner attached for one less step. I also have a 10 pound tank mounted on the back of my camper and run a hose to the skottle to power it.
The main difference between a skottle (or similar curved/dished cooking source) and a flat grill or any frying pan is the skottle has different heat zones which allow for cooking of multpile items at the same time. Cook your bacon, then push it up to the side, then cook your hash browns and move them up, then cook your eggs. All on one surface that is easily cleaned.
