BE112 attys

[cos]

Hi can someone please explain to me about the BE112 attys? Hear lots of good things about them. are they similar to the 801 or 201 style? will they just screw onto a 801 post battery or an adapter? And why the copper? does that make it better? thanks for any info as i really know nothing about these. if they are good id like to get me a few.
Thanks

i got one with my sparkplug. it works/fits my m201 passthrough, and threads with the 801 fitting. the copper looks pretty sharp but mine got tarnished pretty quick. throat hit was decent. mine got a pretty bad burnt taste after a few days but im not sure that happens alot, as ive only had the one.
