This post talks about an EVOD device (not the same but that's alright) pulling/hitting too hard. Users suggest that some of the air holes are clogged... I wonder if I could just cover mine.... I wonder if something isn't tight enough (or too tight) from when the girl showed me how to change the coils and fill it?
Has anyone ever had similar issues, and resolved them, after changing the coils?
Sometimes a coil change can help but that is just not a super strong device. You are using the VOCC coils? I know they used to come in 1.5 and 1.8 resistance. I'd recommend a different device. I use a Kanger subvod (mega I think they call it)with a toptank that I carry as a backup.
Kanger SUBVOD Mega Starter kit (if you look around you can find it for much less expensive)
It is a very similar concept so you would not have an issue using it- built-in battery (better battery - lasts longer) with a tank that you refill and can change the coils but it is a more powerful device, has a better coil
and you can grow with it so it can save you $'s in the long run.
For example - you could use the megavod just as is with the drop-in coils like you are now -- and you will enjoy it much more. Good flavor, good vapor. There is more of a selection of coil resistances so you can experiment with a few different levels to see which one you like best.
How you can grow with it is that the toptank mini is a real decent tank and can be used on other batteries or mods as you grow plus as you grow you can experiment with temperature control mode which takes a different coil PLUS if you stick with it you can go even more advanced. You can even learn how to make your own coils with it. If you are cost conscious that will save you even more money because if you do go that route you would not have to buy the more expensive coils and many of us agree that you get an even better experience if you make your own coils.
Of course, right now you are concerned with finding something that works as is. Since you tried in the past and then stopped and then liked the Juul I think you need a better device to start with to help you succeed.
My opinion.
