If this is the mini-cig that is the same as the Yentl, then it has an open atomizer, as you said; but it's easy to drip actually. Just holdthe bottle upside down until a drop has formed, but not fallen yet. Before it falls off, touch the steelwool-bridge on the top part of the atomizer, and your drop goes right into it. Not too many drops for this small
device though: 2 or 3 are usually enough (except right after cleaning when it's very dry, then it needs a few more; but give it time inbetween to transport the first drops before giving a few more then).
Also, if you want to fill the cartridge, you could try this (should work if the model is indeed the same as Yentl): take one of those big sturdy paperclips (those almost fingersized ones) and bend it open. Then push the wire into the hole at the top of the cartridge (through which you breathe) and push firmly. The small cartridge will now pop out - you can easily fill it now - then push it back in using the plug that closed off the cartridge when new.
Hope these things work for you
