Ok so here is my issue, I have a couple of kanger protank 2 tanks that the stem near the top cap have snapped. I found these on myfreedomsmokes. https://www.myfreedomsmokes.com/cle...-2-replacement-top-cap-w-drip-tip/?fullSite=1 I was wondering if anyone knew of any other sites that sell kanger protank replacement parts.
