Slap Ring?

[mrbass02]

does anyone here use/used a slap ring? does it make a weird sound? Is it fun/easy to play with? Does it help you slap better or what?

It won't make a difference in your playing, but you might enjoy the tone.

is that the thing that German hair-metal guy used to hawk back in the 80's?

I remember thinking that would be a cool thing to use, not so much for wanky NAMM-show flash but rather for avant-garde noise clankadifferousness.
