i find the easiest way to fill the bloog/volt cartos is to simply open it, drip 5 drops while holding the cartomizer at an angle and rolling it , wait a few second drip 5 drops and repeat . a clean bloog/volt carto will take 30 - 32 drops on the first fill , for top ups , just drip a few drips in i find 8 is usually plenty for a refill but if u ever get to much u will see a drop of juice come out the bottom just blow it out into a tissue and dry the bottom and connect to battery simple not messy , i find condom method messy
the mouth piece is removable for easy filling
