That's the beauty of cartomizers though, it's a simple matter of popping a new cart or refilled cart on and be done with it, no paper clips, juice mess, or stuff, just pop off and pop on the new one. Refilling is easy as dripping in the cart easy enough I bet I can have my 10yr old nephew do it. If you want hassle free
vaping then the cartomizers are the way to go, period.
I can't understand the stubborness of the 3pc users, they act like we are trying to sell them the friggin Brooklyn Bridge or something. They cling to those inefficient stone age E-cigarette design that is nothing more than a Molotov Cocktail minus the gasoline, but the design is just about the same, put some liquid in a cup, stuff a rag in it and apply heat obviously for different purposes....
The fact that you have to mod the 510 right from the get go to get any kind of real enjoyment from it is a joke. I always ask them if they would buy a new automobile that you had to mod for it to run properly because it's pretty much the same thing other than price, I would not buy a new HDTV or something that I had to mod to make it work right either.
It really is funny, I suppose some people either are happy tinkering with their toys, and that's cool their are people like that in the world, and if that makes them happy more power to them, but I think some of them just don't want to admit to choosing the wrong model and have not tried the 2pc models. I can get that too but there does come a time where you cut bait and go to another spot and I try to encourage them to give it a go. I have not touched my M401, 510, or mod since I got my GreenCig model which I prefer over the KR808D-1 which is a fine cartomizer but the GC is better, I don't get that cardboard taste from the GC carts and the carts are vastly superior in design engineering and perfomance, in my
opinion.
Once they do try these I would imagine many of them would realize the error of their ways and drop those 3pc models like a hot rock. At this point I am happy with my GC and I don't see myself buying another model until someone comes out with a better model than the GC that I use now. I try to recommend to noobs that if they don't get the cartomizer with their first kit purchase then it would be a great idea to get one the next time they are looking since 99% of us have more than one kit.
Then I found this forum and went to a 3 piece and liked it a lot more and it got me off the cigs. After a few month I found the kr808 and got one of those and now I like both the 2 and the 3 piece. I think if I had found the kr808 first, I wouldn't have needed to try the 3 piece cause I really like it. But then, I don't mind fooling around with all the topping off and refilling with the 3 piece, so it just depends on my mood which one I use.
