I had been wanting to try one for a while but never ordered an ego one mega. I got an email from 101 last week and they had them on clearance for 14.99 so I grabbed one. I kind of miss the old tube mods. There is no adjustment on it. Just push the button and vape. It's really a pretty decent vape. Even with the airflow open all the way its a pretty restricted flow but its not bad at all. Not to mention it's a lot lighter to carry in my pocket at work. I don't know if I'll be buying coils for it but was thinking that maybe I'll use an rta on it after I use up both coils.
