Brewdawg1181 reads my mind! LOL. I did quit using the Aspire zelos kit and it's not a bad option, I quit with that setup so it must be doing something right, LOL. Full disclosure I don't vape that kit now, but mainly because they are now the husband's quitting setups.
There are some really nice other options out there now. A lot of folks like the pico kit, although in the newest version really, the tank is not MTL. It's not a bad mod to have, period though. Maybe not the tank. The Innoken Zenith is really an excellent tank as well however. I think it has a lot going for a new user, ease of use, easier fill system, larger capacity with still great flavor, good coil life, and etc. I'd say the flavor is equivalent to or slightly better than the N2, and I think it's user friendly enough (in fact more than the N2) to be a great starter tank as well, and the larger capacity can be nice.
I also recommend a few tanks that take the Joytech CLR coil at 1.0 resistance. The magic is in the coil though and sometimes you have to buy the coil separately from the tanks. But, a couple tanks that are decent and fit the coil would be an Ego One Mega V2, or a Tron-s Tank. They are bottom fill although not a terribly difficult bottom fill, and I'd probably say that I prefer the Ego Mega one over the Tron. Also 4 ml capacity, coils have longevity and can be rewicked pretty easily as well.
Another kind of unappreciated tank is the Ijoy Elf, (IMO) it doesn't get the respect it deserves. It's like a N2 only it "fixes" the N2 problems, much easier topfill system, true 2 ml capacity (the N2 can only be filled to about 1.7 ml if using the fill line (and you should) and the topfill is okay but can be a bit finicky on the N2, the Elf comes with proprietary coils but also accepts the N2 coils, and it's a nice tank if you are looking for something smaller.
You have lots of options, that can be good and bad, but really switching to any of the other setups mentioned will probably give you a nicer experience than you are getting now, and once the equipment is procured, you will likely get better coil life and a better vaping experience.
Best of luck!
