First off when it arrived the top cap 510 threads had a burr and none of my 510 connector atomizers would work, I decided to get a 7 x .5mm tap to fix it (I wasn't going to wait over a month again for the RMA)
Got the tap in, fixed the threads (cut my hand slightly in the process), they were far worse off than I thought the hole was tapered or something because the tap barely made it thru
Dropped my kick in the 18650 tube, put an eFest 18500 flattop in it, found the tank wouldn't screw all the way down nor would the end cap, the center contact pin is too long (and the body is too short)
I ground off approx 2-3 mm of the center pin, tapered it and re-assembled, it all fits good now, however I tried out the 18500 tube with the kick and a 18350 button top battery, I couldn't even screw the end cap on (the threads wouldn't engage)
The solution to all this is to have the manufacturer cut the body tubes 3-5mm longer then thread them...otherwise they are TOO SHORT!
I don't want an RMA on this...I am VERY displeased with this item even though I got it to work (only in 18650 mode with a kick a regular battery will not make contact)
I do like this MOD but the problems are IMMEDIATELY apparent, so if you can tell the manufacturer to cut the tubes just a little bit longer and all these problems will cease to exist and your Caravela mod will be PERFECT (well unless you want to get them to make it 21mm in diameter rather than 22, but that's a different gripe all together)
I just though I would let you know that the manufacturing defect of 3-5mm too short body tubes will quickly upset people
My only complaint about the kayfun on the VTR extension is that it's giving me tennis elbow...
and ever so nice to read. Thank you!
