Lol, well I know that for next time. When you start vaping it’s impossible to know and you rely on the shops if you don’t know about this forum. I bought 4 of the same Smok Spiral plus tanks in less then a week, because I didn’t know you could buy refill coils. The dude in the store must have loved me. Each Smok tank came with 2 coils and when they both gunked up (a day each as I am on super sweet Nasty Juice) the guy at the shop simply sold me new tank packs as they come with 2 coils. I now have 4 Smok spiral plus tanks (4ml each so he was also clearly getting rid of older stock) all sitting here doing nothing as they are pretty meh for me now, especially since I learned more, watched reviews online, and since I have found and learned to rewick the amazing Wave RBA for my daily walk arounds and a Dotrda 24 for home, so I’m good for a while now... rest assured I complained to the manager since, and that dude working there (on commission clearly) was since sacked.
