When I smelled them in the package, the scent was very good! They smell like mango and made me want to buy them, plus they have a natural aroma inside. But if you light one in the room, it doesn't smell unless you have it next to you. You need to light many of them to make the room smell. So it's probably not worth it. But even just the packaging smells without lighting them. They smell perfect. They last three and a half to four hours and do not smoke.
