Hey
I just received these tonight.
I'm using the first one on a ProVari. Keep in mind, the experience will depend greatly on what device you're putting it on!
My ProVari shows the resistance at 3.9ohm!
That is VERY high, and I'm sure on a eGo or other 3.7v device, I'd be sucking wind with this (I've only tried one of the five I ordered, and I've read mixed reviews of some people experiencing leaking problems, and other problems on some of theirs, so take what I write with a grain of salt. If anyone's interested, I could repost my opinion after a few days, and after trying a few of them)
With my ProVari set to between 4.8 and 5.2v, I'm getting excellent vapor production, and a very warm vap. In fact, at 5.2, it's a little too warm!
At 4.8v, I'm really enjoying this. Not sure I'd take it out of the house, as it seems like it would leak if tipped over, but for around the house, on the computer, watching the boob tube... it's not bad! Not bad at all....
Hey, at $11 for five of them, if they all work like the first, and if I can refill them 3 or 4 times, it's pretty economical.
