Exvape Expromizer V4 MTL RTA

V4 on the Kroma-R. Gona take all these tips before I show my k@k wicking lol. But none the less super impressed. Versus my Hellvape MD and Berserker Mini, the V4 is just a on another level I still can't understand this that there is so much of clean crisp flavor tasting desert notes that I couldn't get before. Using the VV Superfine MTL coils for nowIMG_20200918_231305.jpg IMG_20200918_231320.jpg

That combo of mod and atty is gorgeous, actually looks like something that could be from the @Rob Fisher HE collection.
 
You're right...think its much better now

And same here wow suits the Expro like it was made for it.
 
This is the first MTL atty I've bought after lockdown, last one I bought was a hellvape MD end of feb and although I liked it, if you didn't have enough wraps or it wasn't spread out properly it would leak and ended up not using it at all and left MTL altogether but since being back at work and not having time to leave my desk I needed a MTL for stealth vaping, dug up trusty V3 and it was did a great job but wow after using this V4 for about 2 hours now, its superior, amazing smooth draw and great flavor on simple 26g kanthal round wire @ 1.29 ohms.

Anyone else having wicking issues on the Expro? I’ve yet to go above 15W but am getting hints of a dry hit quite often. Tried some different wick options - more, less, combed tails etc but no major difference

@Darth-vaper have you tried shortening the wick so that it does not reach the bottom of the wick ports, just slightly raised?
 
I use Cotton Bacon V2, thin it out a bit so that there is just enough cotton to fill the wick port from side to side, but not tight, lightly tucked in from the sides so that the ceramic tweezers's tip does not go in tight and I dont force the cotton down, almost a half-dam method by just pushing the cotton from the side so the ends slips into the ports

I think everyone has given great tips and you can really go wild when thinning out and rewicking because top airflow won’t leak but you may get gurgling. I would fill say a 1/4 and if it vapes better then fill to the top.
 
I’m using TFC Elite wick, which is all I’ve used in my RTA’s for the last 2 years or so... maybe I need to try something else

I know it may sound a bit obvious but have you opened up the juice flow control enough, maybe it's not fully open, sometimes the atty might spin a bit when you put it in your pocket or you refill it and forget to open up the JFC?
 
I have - had it where I can see the end of the wick through the juice hole, so not touching the base

Is the cotton loose inside the coil not too loose but loose. Cause if its in too tight its choking and wont wick right. Make it a bit loose inside the coil and same with the points must not be too tight inside the juice ports. Hope you come right and what is the ohms on your coil, what wire are you using.
 
Thanks for all the suggestions guys. I will try using less wick through the coil, and also try CBV2.
Currently using a plain round wire 2.5mm 26g kanthal about 8 wraps coming in at just over 1ohm.

I was worried about the Expro's 2ml glass but its actualy enough cause im vaping it and the 2ml is lasting me a day ok i do change now and then. But how far are we to getting the bubble glass locally. That will make it 2 days lol.
 
@Darth Vaper Was going to check about Juice flow but @CashKat88 beat me too it, other than making sure the juice can flow under the wicking and following the higher VG of your juice the less cotton needed rule i really don't know. I wouldn't thin out too much where you get gurgling. Nothing worse in my book than a gurgling tank that can result in a gob full of e-liquid also once you have a tank behaving like that juice flow control or not they have a tendency to flood both deck and airflow out after a fill. Just trial and error soon it will just work great after a re-wick and from then on just a repeat of the process each time and you will wonder why you had issues in the first place!

I was just thinking that if you put too much cotton through the coil, even if you thin out your wicks it will still choke the juice flow and dry hits will definitely occur, cotton needs to be somewhat tight but not so tight that it's hard to get through, alot of dl tanks don't have issues when wicked very tight (some do) but MTL tanks don't like it because of limited airflow and if wick'd to tight juice doesn't get to the coil or just kinda burns and bubbles when it gets to the coil.
