I was thinking of buying this trick, is it worth it??? How clean are you at the end???

You are, pretty much, as clean as you want to be. As long as you do not mind sacrificing a bit of the gimmick.

Yeah, I agree this is an awesome trick. To tell the truth it is my hook up. If I am not mistaken I do believe this is the Fearson hook up. Can anyone clarify this? Thanks and I highly recommend you get lite flite.

One problem I have is turning the *** thing off! It floats in my pocket and just sits there glowing. They should create a switch at least

It's a clean one.
It's very nice effect and you can end clean.
It's like Steve Fearson's floating cigarette.
