I used to love the dk tab when I first started
vaping. I just got 30ml of the concentrate in from rts. Mixed it up at 5% and after 2 days, it's pretty darn strong. Probably need to steep it a lot more but definately too high for me. I'm going to blend it down to 3%. I remember it easily permeates a mix with just a couple drops of premix. My wick is toast now, can't change flavors in the tank like normal with this one. Its flavor just sticks around even after 2 tanks of other juice. I'll have to build up my retired protank just for this flavor.. This 30ml will probably last me years. It was only 2.50 more than the 10ml so picked it up but wich I would have got te 10ml and put the other 2.50 toward the hangsens to try..
after you try the tfa/pa dk let us know how they compare.
