I originally bought the Black's Pk Ring. It broke rather quick during regular use (vanishing a
steel core quarter from spectator's hand) So Penguin was kind enough to send me the Wizard PK as a
replacement (FLAT STYLE) Personally I think the ring looks nicer than the band style, and the
effected magnetic area is a bit larger. Overall, I'm VERY happy with this one. If you're looking
to get into PK, pick this up, you won't be sorry.
