I do not as I have their three-burner natural gas grill. But I would offer that it would be difficult to clean once made dirty. It is like the small grills that use a small bottle of LPG to cook. They don't produce enough heat as you would want and then they are hard to clean. For example, you can cook a steak, but there is not enough heat to sear the sides.
Then again, having one and having to deal with it is bound to be better than not having one at all.
Cheers!
