OK, so I spent the evening with my first CE2 cartos...
1) They are a pain in the .... to fill... the little filler thing that came with them won't pass juice... it was clogged from the start... thank goodness Desi gave me a blunt plastic needle for my syringe otherwise I'd still be trying to fill one.
2) The draw is a wee bit stiff for me, and that's a personal thing because I like it to be looser than most people
3) The fill DOES last a long time. Once they are filled, I chain vaped 1ml of juice in about 50 minutes, and I could have gone longer... these carts are pretty stingy with the juice, and don't need to be topped off as often, and that's good because filling them makes me shudder in fear.
4)They don't wick fast enough to use em with 5V... it gets ugly REALLY fast.
5) The Flavor on 3.7Vs is outrageously good. On 5V it's pretty bad, and harsh
SO, what do I think? In general, I don't like them. I love the flavor, I hate the hassle of using them. I'm going to put them on a variable using the NotCigs.com Terminator and dial in the optimum voltage for them, which I'm willing to bet is right around 4.1V-4.2V under load, or so. When I get around to that I'll let you in on my findings.
I'm glad I tried them, and I'm not surprised at the results, there has been a lot of talk about these and my experience seems to be consistent with most peoples results. I just had to try it myself.
