I recently bought a 900mAh starter kit which came with two clearos. Now that all my juice has steeped and is vapable, Two clearos are NOT enough!! I need to get 'more', but am not sure if I should go with more clearos or get tanks. I was thinking at least one tank for my 'all day' vape. Advice is welcomed including what types (vivi nova, Kanger, etc) This kit is ego/501 threaded. I also discovered that just because something says its a 501/808 adapter its not necessarily true if you get it from the place that sells proprietary cig alikes...it works on THEIR batteries, but not 'standard' ones...threading is just that little bit off...as I found out this morning trying to use my new dripping atty with their batteries....
