Cartos and attys are not the same thing
An atomizer is used with a cartridge aka cart, or on fairly well sealed manual batteries an atomizer can be used with a drip tip
A cartomizer aka carto does not use an atomizer. It is a combined 1 piece disposable cart with internal atty.
I don't drip in a drip tip on 808 cartos. The 808 cartos I use all have a defined center air channel. The
juice would aim for that. I remove the drip tip (which I use only as a mouthpiece) to add
juice.
if you want to test juices on a manual 808 battery, use a DSE901 standard resistance atomizer and a drip tip (no adapter needed)
I only use cartomizers with my favorite juices. I keep a carto damp with the same or similar
juice until the carto doesn't work well any more then I start a new carto. I can usually get 1 week of use out of my main cartos, longer out of the ones I vape rarely. I am usually alternating two cartos with contrasting flavors. And a have a small number of other cartos with flavors I don't vape as much.
