I also use vapor4life cartomizers. I am in love! What I do is pop the caps off of the cartomizers and put a 901 tip on them (cut 1/4" to 1/2" off the cartridge part of the tip and remove the filler so that the vapor does not get caught in the cartridge holder of the tip and so the tip doesn't hit any part of the insides of the cartomizer). Anyways, I use about 1 cartomizer a week. After
vaping out the initial liquid I just drip liquid onto the cartomizer's filler. I am a heavy vaper and I can get a whole week before the vapor drops or I accidently burn the insides of the cartomizer and make it undesirable to
vape. For me, I would go through an atomizer every 2-6 weeks, but after a few days I would have vapor drop off and bad flavor come in but I would deal with it as long as possible because of the price of atomizers. In fact, I opened a brand new 901 atomizer a few days ago and it lasted 2 days before I got so angry with it I chucked it out. It is much easier to throw a cheap cartomizer away than an expensive atomizer. And it's always like having a fresh atomizer for the whole weeks I have the cartomizer out. It's always wonderful flavor, always large amounts of vapor...heaven! My only issue is, with non-premium cartomizers you do have to "break them in", the first few
vape sessions are weak as you break through whatever gunk has settled on the coil during storage (that's my guess at least). But the premiums vape like a train out of the package! I love cartomizers! I have not tried the 510s or the 4081 (?the cartomizers that work on the njoys). But I might eventually just to say I have!
