After resolving a minor issue, my new Tobeco KF v4 is the most awesome tank in my collection. I have an authentic kayfun V5 as well, but that's more of a DTL hitter. I love the easier 1/2 turn on/off JFC of the V4. I purchased a sub-ohm kit, but I don't think I'm going to use the center post portion of the kit. I just don't want to lose the MTL action that I'm getting now. The flavor is over-the-top! Fit and finish is the best I've seen form any cloned atomizer. Been using it for 2 days without issue.
