I have an iTaste VV and love it so far, but I often find myself getting tired of flavors before my clearomizer is empty. What is the attachment called where you drip only a couple drops at a time onto the wick/coil so that someones less often desired flavors can be vaped more efficiently? Also what exactly would I need for my iTaste VV in order to run this setup? Do I need a special drip tip as well?
