Kayfun lite will be the best...
for beginners
I disagree. The Kayfun is a real PITA compared to the Squape R.
Just a few advantages of the Squape R.....
1. You can remove the deck without having to empty the tank.
2. Wicking is far easier. Almost fool proof with the Wide deck.
3. The deck is grooved so you can just lay your pin/screw/coiling tool into the groove with the coil on it and screw the leads in place. Makes for perfect coil placement and alignment every time.
4. Far more adjustable airflow. Everything from a really tight draw pinhole to easy lung hits.
5. Can handle high ohm and subohm coils down equally well.
6. Swappable decks which allow for restricted juice flow, wide open juice flow, single coil or dual coil, and even one that works like a dripping atomizer.
7. Glass tank so you don't have to worry about tank cracking juices at all.
8. Metal outer sheath so you don't have to worry about breaking your glass tank if you drop it.
I've got 3 Kayfuns. Based on some recommendations here I just bought a Squape R. I'll probably never touch my Kayfuns again. The Squape is just a heck of a lot easier to build on, easier to wick, has better airflow with a wider range of adjustments, and being able to remove the deck without emptying the tank is a godsend.
