I had never seen one of these reverse flow incense burners, so I had to get one. I had a family birthday coming up and new this would be a perfect gift. It was! I tested first at work just to make sure that it did. Everyone at work was a intrigued as I was. It really does flow down just like a waterfall. I gave the gift and have gotten nothing but positive praise. Make sure you get the correct type of incense as well!
