Before I purchased, I didn't have much confidence it would be any difference from any other quality cotton. But boy was I wrong! It wicks really well, It's easier to work with and there is virtually no breakin time. Plus, the taste is great. It is now very difficult to use anything else. You need to give Fiber Freaks a try. You will be convinced.

Fit my Kayfun Lites and don't rust.

Bought to go in my eVic VTC Mini micro USB socket to keeps out lent and dust. It looks good too.

It looks and feels cheap. Kind of a felt texture to it. The top has just enough space for my 22mm Kayfun. A 23mm might have a time screwing all the way down. It's very light in weight. The display is bright with all the functions like Battery Level, Ohms, Volts and Watts displayed simultaneously . After firing, it remains illuminated for about 20 seconds. Standard up and down operation of the buttons. It vapes well enough but it remains to be seen how long it will last. Overall, I like it.

I realize telescopics are not for everyone, but what can't be denied is the build quality, ease of use and the exceptional performance of the Tesla Biomech. It surprises and dismays me the lack of sufficient attention this mechanical mod get. I think this would be one of the first mods recommended to new vapors looking to get into mechanicals because of it's ease of use and it's ability to accommodate all 18XXX batteries. This is the best mod and the best performer I purchased here and I have many. In fact, I purchased a second thus this second review. The Tesla Biomech deserves better recognition!
