Check out post #18 of this thread http://www.e-cigarette-forum.com/forum/smokestik/126895-a-2.html There is a cut away of a KR8 and a SS carto, as well as a well done experiment on the burnability of the internals. Wow is all I can say! Deffinately worth the price when you think about it. I haven't had one DOA or one wear out w/ 20+ refills of 8 cartos. Every RN4081 user should have some in their arsenal. 20% ECF discount here: SmokeStik ::: Alternative Smoking BTW, the regular are a bit cigarette like, definately have the taste of burning tobacco, but not too "ashtray" like. The menthol, however, are a mild menthol with a hint of cream/vanilla. Very yummy.
