Hello all. Picked up several of these which arrived yesterday (dang that was fast!).
I'm using these on a 3.7v box mod (i.e. straight up off a 14500) from MadVapes which I built using a dead 901 battery's connector instead of the supplied 501. I'm pretty new to vaping, and do enjoy dripping on my 901 atties, though I haven't yet experienced ones from ikenvapes. The ones I have now are all standard (~2.6-3ohm). I also have a number of 501 carts (1.6 - 2.4ohms).
Of everything I've tried so far, these carts produce the most insanely dense, moist, and taste-filled vapor. I literally didn't know what I was missing! They are almost too much for me on a fresh battery, and I really can't wait until I have the opportunity to build a VV mod to try these out at a little lower voltage. In the meantime, I think I'll be using these after using something else first on the fresh batteries for a couple hours (i.e. my limited voltage regulation scheme for now).
I do have a question...I saw one person mention "replacing the inner ring" on this thread after filling. These are the first cartos I've seen that have this inner ring, so I wasn't sure what do to there. What is the "proper" fill method? Remove that and drip until nearing a slushie? So far, I've just been dropping them down the hole until they start going in slower, which probably explains why I get so much juice back when I first fire them up. That would be my only complaint, but not a complaint for right now as I'm assuming that I'm filling it wrong and/or overfilling.
I also love the draw on these. Most of my SLB 901's feel a little too tight/hard on the draw, and the 510 cartos just aren't smooth like this one.
One last thing - it was a little bit of a learning curve for me with my 901 atties with plenty of leaking and flooding prior to changing over to dripping (after wasting way too much time, effort, and juice experimenting with various cart fillers), so I was relieved to find these work so well wet and haven't leaked so far.
