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.
