Day 2 Vortex review...
I use egos, for this you need the adapter. Curious how the 510s will be. Juices are very thin (low vg). I am a hot boxer, meaning I'll take 3-4 hits on one burn. To me only the 3rd hit is when my egos heat up enough. Now on the to review.
First fill is awesome... But from there the flavor and vapor goes south. After 5 refills, no leaks of any kind, tips fit good, etc... I disassembled the first one for cleaning and I think the design flaw is the wick. There was so much "crude around the wick that I'm sure the liquid is being constricted. I was able to clean most of it and dry burn, but the flavor never came back. If only the wicks were replaceable. (This is the same with the CE2-XLs, but they allowed for
juice flow around the wick when the atty ring was removed.) No leaks after re-assembly. The other issue was my egos. First I think they are dying, second, voltage drop. With the atty so far from your mouth you loose a lot of heat. If my batt kept a constant 3.7v I'm sure the carto would function better. (insert forehead slap here)
I will be cutting the outer tub by a 1/4. 2 reasons, I like a squat cart and with the adapter/tip these are too long. Second, I think the distance from the atty cools the vapor too much. I will leave the inner tube at length so it continues
through the tip for added sealing around the "
tank" area. Will post results later.
All in all, I think the idea is great and with minor improvements (and a better setup

) They will work out great.
