BTW, steaktaco where on earth did you find a $7 ring?
An Amazon seller. I would've paid the precious metal premium for this ring, but ironically this is the only place online that had 316L stainless bands in a 5mm width. Fits perfect, would've been too snug if it wasn't comfort fit.
Correction: only place online until someone supplied the Boone custom rings link above. Nice stuff there.
