Choices? Officially kayfun 5 is made for 0.5 ohms and higher. Check the manual. Have question of the quality of the peek being used if it's 0.5+. RDTA, supreme, even something the clieto does 0.4 yet a £100 tank is limited from the start. I've used v4's and while tank is simpler, it's still missing basic stuff. Should be able to do 0.2 ohms easily. tanks half the price can. Good luck to the v5 crowd. I'll stick things like the avocado 24mm with a notch coil. The price should not justify the product like the v5. The product should simply that good to demand more. It's not. This is not the only tank like this. Squape dream is in the same boat. Over priced and missing steps.
What is the saying " Horses for Courses "
Thousands of these will be snapped up in the next few weeks especially in Europe where the TPD comes into effect on the 20th May which will restrict Tank capacity to 2 Ml .....whether or not this will impact on what we will be able to purchase in future is anyones guess
I will be purchasing 2 having read the contents of the thread and watched the Video Review !
These will "Work" fine for me at what I see as a reasonable price !
Each to Their Own !
