Is it just me or everybody has these issues with this Kayfun ES 3.1 Clone?
1.The Center Pin is NOT exactly in the center and it shorts to the ground sometimes. Mine reads 15 Ohm with no coil and wick. I had to file the head of the positive bottom screw (center pin) to prevent it from touching (shorting) to the side of the 510 thread connector. Because it has to be exactly in the center, but it is NOT in my case.
2.The Center Pin screw come all the way out, when you unscrew it it should not do that.
3.This Clone does NOT have a Bottom Filling Screw so you couldnt fill it up from the bottom.
4.Side Filling Screw? It is NOT Fillips, NOT Flat, NOT Hex, NOT Torx
It is a round hole screw head. Although, I was able to jam a small Torx and unscrew it, it appeared that there is another small weird screw behind it or I broke the screw and it is the other half of it. In any case, I could not fill it from the side. I had one option left only: Fill it up from the Top. The worst way of filling Kayfun because when you screw in the top back into the Atty it will create a pressure forcing the tank to leak. And it did leak out through the locked side filling screw. Im thinking of drilling the base and installing the Bottom Filling Screw myself. Unlike the EHPro Kayfun 3.1 Clone that has the Bottom Filling Screw, the Side Filling Screw, not Issues with shorting center pin, it also does not come with the Drip Tip Adopter, and therefore you will not be able to use a standard Drip Tip. This. It was shipped in a plain plastic bag no box, no spare parts, no tools, no wicks or wire.
