Do you mod your ce2s to drip, because if so, I would love to know how.
Actually, I have dripped a CE2 before
If you're ultra lazy, you can, just stick on a drip tip and literally just put liquid down there. It's so sloppy though lol but I have done it when I just couldn't be bothered finding the syringe or taking the seal out. All that happens is some liquid goes down into the wick hole and some just kinda sits there on the inner seal until it finds its way into the wick hole too.
Also, you can literally just remove all of the seals, stick on a drip tip and you just run the liquid up the sides to simulate dripping. Just tilt it sideways and it'll wick when the liquid is next to the cup. Easiest way to do it really but as you can imagine it's not very portable. Must be kept upright. I've also done it this way.
Best way is to cut the seal or put it back in upside down (right now I'm using the mouthpiece seal as the "inner" seal instead so it doesn't even have to be the actual inner seal once you've taken it out). Just whatever stops it all coming out at once. Quick one second tilt and hey presto, wicked CE2.
One last way (yes I've done this too to test flavours when I was too lazy to blow out my atomiser - shameless!) is just to tailpipe the CE2. No seals, nothing. Just direct drip onto the coil (I use 2 drops at a time) and just vape it. Biggest risk of getting hot juice splatters in your mouth though as there's no protection and the coil is that close to your mouth. Have had a few splatters but like I said I've only done it to test flavours when I was too lazy to do it with something else.
Edit: oh I forgot, you can also just use the "doughnut" seal and just sit it ontop of the cup if you want to drip with a drip tip. Nothing's really going to happen to it. Anything not used is just going to go into the CE2 and build up enough you can use to just tilt it sideways back up to the wick. The rest is going on the wick anyway. It is a little...hmm...not precise, as you're going to miss the wick enough times you'll have a little liquid around the doughnut. Why I use a drip tip when I use a CE2 anyway, because you tend to get a little liquid between the seals whether you have them on properly or not.
If there's a point where there's too much liquid in the cup I just suck it back out into the top chamber because I'm using a drip tip and it doesn't get in my mouth that way. Beats wasting it blowing it out and it's going to find its way back into the wick at some point too.
Having a VV device really helps though. If it's too wet just up the voltage and it's vaped off. Harder to clear it if it's too wet if you're on one voltage but sucking it out with a short, sharp pull can do the trick.
Sorry, I'm answering and I don't think you even meant me haha
