Just got mine from Gotvapes today. I filled 7 with my favorite flavors. I do not own a syringe with a needle yet, so I carefully took the seals out. You have to be careful taking the bottom seal out, by gingerly lifting the inner edge in a circular motion until it works loose. 2 out of 7 were really seated tight on there, and I actually destroyed the first one. I just grabbed an extra from my old ce2 stash and it went on fine.
After filling straight from my bottles while angling the carto, and dripping juice down there I replaced the cap, but kept it slightly higher than it was before. once I pushed the flat ring, and the rubber mouth piece back in, It wicked well, with zero burnt taste.
My opinion is that the factory is putting those seals in a little tighter than necessary, so much so that it really is restricting wicking action. I actually accidentally got one back to factory tight, and noticed it when I vaped, with a burning or plasticy taste, but as soon as I lifted it slightly the taste went away. It is an important balance between a hole big enough to let the wick do its thing, and the hole smalll enough as to not allow juice to leak.
The filled fluxomizers are all laying on their side and have been that way for a couple of hours and so far, no leaking.
I have been using 2 egos with the 2.6 to 2.8 ohms and they hit nice. Most of these juices are 80%pg . I do not find the vape warm at all and could handle them a little warmer. Too bad I have 40 more of these coming in a coop. Good news is I like them, and I think my wife will be able to quit analogs with these because she is too impatient to tinker with ecigs. Too bad she doesnt like one of the 100 or so flavors I have currently. I have a sweet tooth and she hates it.
I am finding most of my flavors are quite accurate, and the ones that had throat hit in an atty had a similar throat hit in these. And my higher vg ones had very good vapor, and similar flavor to a regular 510 atty.
I found that they vaped just fine after filling and priming the coil a little, but at first I was a little dissappointed in the flavor, but 30 minutes later, I had the same amount of vapor but nearly double the flavor. its still not quite like dripping on my lr306 but the flavor is surprisingly good. I am a waffle junkie and all 3 that I enjoy tasted good in these cartos.
My only complaint is the black mouthpiece. I really wish it was slightly beefer as far as the piece that you put into your mouth. Maybe I will get used to them, but I prefer the one that comes inserted in the carto, plus when you put it back in, I feel it pushes the cup cap on right where it should be, without forcing it down so hard to pinch off the wick.
I also feel that the pipettes, although a nice thing to have around, is not necessary to fill these. If you have to take all the seals out, its just as easy to use a juice bottle to fill, as the pipette doesnt really fit down into the chamber because its too big around.
Overall, I am pleased, and really appreciate not having primer to wash out.
I feel my success is by replacing the cup. Those filling with a syringe, and not lifting that seal slightly may actually experience more wicking issues.
I look forward to reading more tips on these. If anyone is interested in trading some lower ohm ones for the 2.6 to 2.8 ones that I have, send me a PM. I should have mine within 10 days or so.
Cheers
