So far it's working great! I experimented with a bunch of different tanks, Aspires, Protanks & their variants, etc. My favorite so far is still my Aspire BDC's with 2.2 coils, set at 3.8. Exactly the same as on my Spinners. No difference. I did use the SVD to check all the coils that I have, and there is a HUGE variance in the Kanger coils. A few of the BDC's were off, but most were what they were supposed to be. At this point I've decided that the SVD is fine for at home, but I'm just as happy with the Spinners for out & about. Color me disapointed.

. Rebuilt my rda for the very first time and came out with a single 2 ohm coil. Smacked it on my SVD and have been dripping like a nutcase ever since. I've caught new shiny toy syndrome from this thing. Now I am constantly looking at toppers which match it's sexy
. Either way I'm really glad I grabbed one despite the button fussing I've read about.
