Rib Rings from Bbq Guru - Any Reviews from Here?

[duff645]

One of my emailers that I received this week was from Bbq Guru and showed an interesting new accessory:

Anyone try it yet? 

They say its good for 5-6 racks of trimmed ribs, on a kettle / WSM.  Looks ideal for 22" but in my opinion too tight for the 18"

Happy smoking to everyone!
