Had 3 pakcs of 5 coils each for the kanger EVOD/ProTank. Was trying to see if they firt in a ARO. Just my luck the ONLY 1 of the 15 that had a base small enough to fit in the tank is the one I pushed out of the pack. I stand corrected. Kanger coils don't fit the ARO. There I had my serving of humble pie today. WOW I found something that taste worse the anilogs.
