We've had our companion grill for a couple of years now. The first thing I did was quite trying to use the little green cans of propane. I bought the larger tank adapter kit. It's a little more trouble carrying around the larger tank but worth it.
It took me a while to figure out how to cook with this grille. As the other poster said with my previous grille I was constantly opening the grill to see how things were cooking and turing the meat. With this one you want to leave it closed and only open for turning or when you're eone. When cooking meats I set a timer for when to turn the meat and then again for when it will be done. It does a great job of keeping the meat juicy. But, if you like your meats chared on the outside then this is not the grille for you.
