I've got a couple Falcons. Decent smokers but not outstanding, good bang for the buck. I make my own dry rings from pipecleaners. You need to keep the inside of the bowl hole and outside of the humidome free of gunk or it closes off the draw. For me it's more maintenance than a standard pipe, and running a pipecleaner through a regular pipe works just as well to sop up moisture as any of these better-moustrap inventions. At least Falcons sump is metal and wipes clean easily, unlike Peterson system pipes where the briar sump gets wet and stinky.
I got my Falcons from 4noggins because they had the greatest assortment and the lowest prices. Thinking of picking up a couple meer bowls at some point.
