I just received USPS notification that my two Big Fogger came out of the fog and arrived at Los Angeles sorting facility. Hooray! That's 19 days from Fast Frog in China.
On that note: After building,
vaping and re-building two Big Kayfuns several different ways, several times for several days. I confirm that Fogger V4.??? Vapes BETTER that Kayfuns (big or small)
And that is coming from the Russian that has an unconditional love for Kayfun. I own 5 of them now. (big and small)
Here is my detailed review of
fast tech 30mm (26650) Kayfun Lite:
If anybody cares to read it.
If not - just skip it.
I bought two of them at different time in two different shipments hoping they are from two different batches. But they are pretty much the same.
1. Liquid Capacity is 10 ml, NOT 20 ml.
2. Some genius decided to use Washers under the Terminal screws. Bad idea, those washers create short circuit and both units arrived shorted without
coils. Here is why:
I suggest removing those washers and not using them.
3. Neither the Screws or the Washers are made out of Stainless Steel (They stick to the magnet)
4. Also, when the factory drilled the side Airhole they did not remove Burr from the Center Pin hole, just where the drill bit makes its exit. Thus also creates potential, intermittent short circuit. The Burr must be removed: (it is very hard to capture that burr inside the hole, but believe me it is there touching positive center pin)
5. In one of my units, the bottom portion of the Chimney (Chimney Well) has a crack all the way though.
6. The other unit came with MISSING Delrin Insulator, it just wasn't there.
7. Positive terminal block is machined poorly, the threaded hole almost exposed on one side:
8. I replaced those screws with M2.0 Stainless Steel but my screws had their heads taller by 1 mm and that shorted to the Chimney Top portion, I had 0.27mm wire under the screw head. That means that there is only 1mm gap from the top of the positive Screw and the chimney that is Negatively charged. An other word: It is dangerously close to shorting out especially for those who like to use thicker gauge wires.
Here is the evidence of Short Circuit: (You see those burnt marks?)
That said, over all it is a pretty good atomizer (after you get all the problems worked out)
I have it built with a single coil and with dual coil.
I performs pretty well.
I'm going to open up a Support Ticket for the Missing Insulator and Cracked Well to be replaced.
