I've used Duraflame logs often and consider them an excellent alternative if all you're looking for is "I'm sitting around a campfire" ambiance. I've not had much problem with the smell or having them burning cleanly. It's helpful if its elevated off the ground somehow so air gets all around it.
The biggest problem is that they are boring, and that they are boring for three hours. Once started, they burn pretty much uniformly until they're done or you kill them for good. It's kludgey--and semi-dangerous, according to product instructions--to poke at them and try to break them up. Still, I find them the time savings (and cost savings, given the price of at-your-site firewood) considerable. It seems to me to be one of those "get 75% of the benefit with 10% of the effort" tradeoffs that are sometimes the way to go.
FWIW, I also have a Campfire in a Can and think it's great. Easier than a real campfire but with adequate campfire ambiance. But it's a good deal more complicated to transport and store, and to keep from getting things sooty when handling. Highly recommended, but still nowhere near as easy as the somewhat-cheesy Duraflames.
