I cannot use my vapor flask DNA40 with my Crown Tank, does not detect the atty. Keeps saying check atomiser, no matter what OCC range i put it.

I tried extending the 510 pin from the tank outwards.. it can be pushed out.. but i dont think it was be screwed tight.. So same thing.. once i screw back to the vaporflask.. same thing.. unable to detect Frustrating

My Crown OCC only last me for less than 24 hours, already tasting burnt, and im only firing at 30W on a 0.25 OCC. (Mod is reading it as 0.37)

Yup.. i primed my coil like a wet swimsuit model.

0.25 got flavor.. but flavor was better on my 0.5 firing at 40W. (My current mod only fires max at 40.) I didnt use my IPV D2 to fire higher cos i dont like warm vapes.

Im not sure if my OCCs were  faulty batch cos even my 0.5 lasted me 2.5 days before i got the burn taste.

Can anyone tell the difference between subtank and crown ? My subtank just spoilt . I'm not sure which one to get first . I've never used different sub ohm tank before .

crown rba is pain to set up n prone to leaking if wicking not ngam, sapteng is super easy n not easily leak.
crown occ not leaking but need to be fired at higher watt to get best flavor n vapor n for me it's better than the rba.
crown build quality is osem.
crown flavor n vapor is both top in class, sapteng never can match this.

overall crown is superb tank but prone to leaking is major problem for me.
better get the bellus or aromamizer...

thank you for your advice..

i normally don't simply ask for spoon-feeding, i did my search online, but not really helping but rather makes me more confuse, then i think that i need a conversation feedback from this forum

just looking for the basic idea so that i know where to start from.. there is a huge list of mods and tanks out there, i just want to filter down to smaller options

now u said chips.. wow.. now seems like it boils down to the hardware type.. hmm i need to do more reading

you know, actually i did went to 2-3 shops... but being a newbie in this, (i think they can sense it) they given offers that makes me confuse, and honestly i'm worried they will seduce me to buy something that i will regret, or maybe not original product at high price

now that i have this few in mind:

IPV4s
IPV D2
Snow Wolf
Sx Mini

I will check them out

thanks guys, all these should be useful.

as for the @mugenz checklists:

Does size matter? not really
Budget? i think i can go up to 800, but i'm a bit particular spender, normally looking for good value for money so i would prefer cheaper price, comparable performance with the expensive one
Looks? ermm.. maybe doesn't matter (they all loos not that attractive anyway)
China brand ok or not? i don't mind, best value for money top priority
Finger prints? what?.. got mode have finger print security like iPhone? 
Abit hot when used? i can stand the hot cigarette buds, so why not

Eh, I'd think a IPV 4s, Snow Wolf or any other dual batt mod will do then. Longer lifetime is a huge plus to some people. Me? Eh, size does matter  I'm happy with my D2. Still get a good whole day out of it even at high watt plus, the performance has been superb. Can't really complain for the price point.

Make sure to get an external charger and a good genuine battery. DO NOT SKIMP ON THE BATTERIES. and yes, the capslock was necessary.

i googled vaporshark rdna40, it looks sleek.. it uses 1 battery only? the firing is powerful and instantaneous?

may i ask how much is the price?

oh, when u said overpriced, its been slashed from my list

any comment on Sx mini? overpriced too?

and right you are, Ken! Me too. Although the longer lifetime is very appealing, I don't really like lugging around a brick in my pants. I do have my man purse or Murse™, patent pending, I don't always use it much.
Yes, but the IPV 3Li is newer. See, and that's why we're always confused. 

*Sx mini too is overpriced imo. The price goes more to the build quality. Hell, I could even get 75 watt on my D2 but yeah, the chipset is on a whole diff levels. There's a bit more fine tuning that can be done on sx mini.

everyone does, Ken

Ssh.. Don't ruin the moment, Ken. Also, stock up more veges and some eggs. You're almost out of both.

The longer the manufacturers keep the SS update away, the more itchy I get with Koopor Plus 200W.
