Kanger has already has too much of my money just collecting dust on the shelf. Their tanks are nice but the coils are junk, either they flood, or they burn or they just mute the taste all together. I'm not near bored enough to start making my own coils for kanger tanks or RBAs yet. I followed baditude's lead on the ibtanked tanks and ikenvape cartos and I am very happy I did. I do have an Aspire BDC Glassomizer in the mail and will be comparing it to the cartotank system, but kanger won't be getting my moola again any time soon
