I wanted to get a new sub-ohm tank tonight, though I've had no problems with the artic the past 6 months I've recently run into some problems with it, the ohms kept jumping on me sometimes which was annoying, so I figured I'd check out a new tank. I chalked it up between the UWELL Crown and the Smok TFV4. I get to the vape shop and the guy instantly recommended the TFV4 when I asked what is in your opinion the best sub-ohm tank out now. So I went for it.. Brought it home tonight, vaped her at 45 watts which is normall what I keep my artic at... The thing shines brightest at 80-85 watts.. same wattage I vaped most of my RDA's at. The tank puts out just as much vapor as any RDA I've seen. Dripping becomes a hassle after a while and I think the only argument left is flavor. I guess there is also the whole hobby side of building as well.. but in terms of vapor, it seems like tanks on own par, and almost there with flavor as well. What do you guys think?
