Sorry guys, Little correction, I did not know my Penstyle from puresmoker was actually the RN (per the posters above), However, all the 801 accessories and atomizers for I have ordered from Ruyandirect.com fit it the puresmoker penstyle parts FLAWLESSLY, So that is why I labeled it as an 801.
for an update: I am still using the 801 atomizers and they are working great, I have had a few of the puresmoker atomizers start to produce a weak hit so I have been letting them drain for weeks and havent touched them, perhaps they are dead or perhaps not, I have noticed the atomizers labeled as 801 from RuyanDirect are actually slightly better in performance and quite a bit better as far as vapor production which is kind of annoying for me because there is lots of times when I have to stealth it at work and it now leaves a gigantic vapor cloud :\
I finally got a nice camera yesterday and to test it I made a video of me hitting it a couple of times:

yea see all that vapor, its ridiculous almost, when I vape in my car it is like filled with vapor more so then ciggarette smoke would fill it lol, ofcourse it dissappears very quickly but still its just funny, maybe its just the liquid I am using now, RY4 from Ruyan. The throat hit is the same as from my puresmoker stuff its just there is an excessive thickness to the vapor.
