I had received Black Styrax as a sample gift in a previous order from EA. I fell in love with the smell. So when I saw these big bad boys, I knew I had to try them. It's been burning for over and hour and about 1/3 of the way burned - I literally got them in the mail today. It's smokey in my house, but not overly smokey - I don't feel like I am choking on the smoke. They are well worth the price!!
