Incense Backflow Burners

I remember when these first came out a few years ago and I thought wow!  that is so cool!  And now I have some!

I have a black triple moon back flow burner that is heavy weighted metal and is about 5" high (doesn't come with incense cones) And I also have either blue or black ceramic about 7" high that has a waterfall effect and comes with 10 cones.  

Note: You must use the cone incense with these particular burners
