I bought some Mega carto's when I got my eGo. I've use one, didn't like it. Like King said, it doesn't wick well. The darn thing takes around 60 drops when new. It takes several drags before it starts producing decent vapor. Then if you hit it quickly a few times it starts tasting burned. I tend to chain
vape sometimes and it just didn't keep up with me. As much
juice as it holds you should be able to
vape all day on a couple of them. But you can only vape it to about half empty then it needs to be topped off. I didn't see enough good in it to keep using them. Some people do like them though so wait until you get some positive feedback before you make a decision.
