Although pricey, the migcig 21 with refillable fusion
tanks(2.5 ohms ) ( or fusion max tank ( 1.8 ohms) if you use nicotine) are the best cogalikes i have tried. Their tanks hold 1.3 ml of
eliquid, you can buy ones that you can auto inhale out of instead of button operated. You can buy disposable silicone tips so it feels like a cigarette more in your mouth. They supply a constant 4.2 volts due to a small chip inside of them until the battery charge dies.( unlike all other cigalikes where the power decreases as the battery charge fades - giving a less satisifying vape) And they are 280 - 340 mah depending on the size. Which you wont find much better mah battery size in a cigalike. Dont get the jole joye ones they wont last very long at all, very poor battery life .
The top three cigalikes on the market are v2, halo, and migcig 21. Of all of those, i prefer the migcig 21 due to the chip inside. Also the hot pink colored one really feels like a cigarette due to its texture. Just remember to buy a skinny syringe so you can fill them as they have narrow tanks.
Im not sure if you can use nic salts in them, but its preferable to use the fusion max tank for nicotine. Since it is such a small device, you will want to use very simple flavored ejuices to get good flavor, like candy watermelon, mango and peach, orange creamsicle, banana split, golden ticket tastes nice in them too. Just no complex flavors like bakeries.
I vape them at 0 nic when i go out with the girls , they arent bulky and easy to throw in your pocket. They do have amazing flavor for being a cigalike. Not much difference compared to a nautilis mini with some flavors, actually.
You can use pg or a variation of pg and vg in these, to a max of 70pg/30 pg. I suggest going 50/50 vg/pg for best flavor and cloud output. You will get a decent sized cloud from these things, like the vision spinner at 4.2 volts, and their tanks are pretty darn good. Dont be afraid to have some flavor in your
ejuice, just stay away from juices with daap ( diacthyl , acetoen, acetyl propyl, fruitoise) and you will be ok. Most eliquids dont have these chemicals unless they are custards, but its always good to check with the company.
