I too have never been a cartomizer user. Ever since LR atty's came out, I made an internal promise to never use a regular atty again. I was using a 900mah eGo kit, with drip tip and LR atty and life was good. At at that point I realized I did not want to drip constantly since LR's burn liquid like there is no tomorrow. So I purchased the wetbox, and while it looks great on paper, the application itself is not too good. Don't get me wrong, it's a great little mod, but like some others have mentioned, you can build the same thing yourself, with little DIY experience for about 10 bucks. There is no need to buy extras since once you learn how to make 1, you can make 4 after you've learned to make 1.
The first time i tried the wetbox I used it with the regular cartomizer that came with it and hated it. The vapor was there, but i was so used to LR attys', that regular cartomizer tasted like nothing! I mean, i know the liquid was in there, but i was so used to heavy/hot vaping from LR that it didnt even compare. What i did was fill the cartomizer first, and I was planning on using it until it's dry, then try the drip feature and see how many drags i can take after hitting the bottle 3 times...but I didnt get that far because I felt like i was vaping air and nothing else. I ordered LR cartomizers from clouds of vapor (1.8ohm), so I'm hoping they will work better than the regular cartomizers....because they suck totally. 1.5 ohm is actually too strong and burns juice too face, so i'm looking forward to seeing how 1.8 ohm will work.
I'm also looking into this , this seems like the only thing i would ever need. since all I'm really trying to do is avoid dripping constantly.
