I've got the Arctic, and it's ok to pretty good, depending on the day, but I've not been particularly happy with the coils. They claim to run up to 80w on the .5 and 100w on the .2, and neither come close. I can occasionally get 65w out of the .2 without getting a burnt taste, but that's only with a new coil, and I usually run around 45-50w. I can't take huge hits at 50w or it dry hits terrible. Coils don't usually last over a week or so, and I've gotten several bad ones that gurgle and leak because the wicking wasn't installed properly. When it's working properly, flavor is good, and I can do some decent clouds at 50w. It is a pain to fill though, two small slots. I'm looking at the Smok TFV4 as my next tank, I want something I can run at 75-80w and not get dry hits. I've had a few Arctic coils that got a nasty burnt taste after 2-3 days, vaping about 5ml a day. Overall not a bad tank but could be better.
