0.6 ohm isn't bad for most folks
@Hinata-Chan, you'll get some warmth and a decent amount of vapour.
If they sell single coils it's worth a shot, at least that will try to keep costs down as best as possible.
But remember to prime the coil well by dripping a very small amount of liquid in the wicking windows and the centre of the coil to get it nice and damp, a couple of drops is all you need though.
Insert the primed coil in the pod, fill with liquid and let it stand, and without turning the mod on take the occasional pull on the vape which will create a negative pressure and help ensure the wicking to become fully saturated.
30 minutes is about the shortest amount of time I would advise you to prime the coil, as if it's your only mod you don't want to be without it for an extended period of time.
But the longer you leave a coil to prime is better in some respects, as you can just leave them at one side and don't really have to do anything else. Just let Physics take its course.
