I have only been
vaping for a little over two weeks, and have tried the 901 and the 510. Personally, I prefer the 510. But, it is all about personal preference, my mother in law prefers the 901. I would suggest you read all the links in the sticky from smokyjoe
http://www.e-cigarette-forum.com/forum/new-members-forum/37186-great-info-new-members.html. I spent a couple weeks reading this forum before I made a purchase, and still ended up changing to the 510. And, thinking about getting a mod or an eGo. I also found out that I did not care if the
juice tasted like
tobacco, actually don't like the tobacco flavors. But, that is about personal preference, too. Part of the fun of an ecig is being able to try new and different things all the time. They definitely never get old. As for snus, I tried it and couldn't quit the analog cigarettes. However, I quit smoking after 25 years the day I got my ecig. For some people, it does take longer.
