Ok so this is a mega reply post as I've been too busy to get here more than once a day right now. I'll snip everything I can to keep it shorter
i still think the cartos without the wire [your yellow one] perform a little better. is that next on your try-out list?
one more question, with your huge selection of cartos have you come across any identical to the truemans?
I'm using the yellow one right now. I'll let you know what I think when I've used it for a few days. Actually right now I like the black one better, at least for the moment. The Trueman ones with the wire are similar to Kanger cartos, but the Trueman ones have much better filler in them. I've never seen another 4081 built like these. The filler reminds me of the filler in the SS cartos. The yellow Trueman ones with the coil, I believe are the same as GP ones. I just got some GP ones so I'll use one of those and do a side by side on both of them when I'm done. GP's come prefilled though.
I know there has been some disagreement on this but I just got the Good Prophets 4081 prefilled and they are identical to these (horizontal). Same yellow color, same caps, same everything.
There we have it. Thank you Neo!! Now I don't have to do a side by side
i believe there was a difference in filler material compared to the gp cartos. katya and/or ww had them side by side.
if your gp cartos just came compare the materials when you're done
Ut oh now we're back to a side by side

Neo can beat me to it
Ross says he just ordered the 510's. But this thing about exactly which style of Truemans people will recieve appears to be a little confusing. So it would be good for him to know exactly what ya'll want.
Thank you Lori, I'm so happy you keep on top of all this

I have not received the Trueman 510s yet to know what they are like. Anybody know if they have the wire in the center or the horizontal coil?
Also I received my Aqua Vapor 510 cartos. They are SLBs. I thought they were suppose to be something different. Did I get the wrong thing?
i believe ww is getting a 510 trial carto from clumsy who participated in the trueman co-op and was willing to donate one carto for our experiments
With the holiday weekend I'm sure mail is being slow, maybe I'll get them tomorrow. I'll report when I do.
I got my mega cartos today and am very happy with them.
Oh cool zelda!! I made such a mess with mine the other day that I sat it off to the side until I have the time to try again. The mess was totally my fault, trying to rush things. I have some blanks coming as well.
Welcome. Zelda - these....
....really do work nice for these cartos by a top fill. You just have to make sure you make it through the middle sealed hole. So far, I've never had any ejuice come out the batt end. I suppose you could do the batt end plug and spin method too if you really thought you needed the full 5-6 hours without refill.

I just got mine in today, thank you for suggesting those!! I already ordered 3 more so I can have them for all my different juice flavors. They sure do make things easier, no matter what kind of carto or even if you drip!
Happy Vaping!!!
