I got the 51 unfortunately , and I was having fun with it my fist two weeks, esp in stores , you wouldn't believe the panic it caused , then I would put it out with my tongue, lol the looks I got . then I found this site and I am getting the riva , but I am keeping the 51 just to mess with people, lmao .
I figure I owe the smoking nazis, fake coughers, nose wrinklers etc a whole load of payback! Mind WILL be played with! =)
