So I ordered 3 Dual Coil Ego Mega Clearomizers from madvapes. I know they that sometimes they need to be broken in but this thing is harsh. Really harsh and not much vapor production compared to the ego tanks that I have been using. I have been using it for about 4 hours and had to put the thing down. Is it possible that the one is bad or is this normal? I was going to try a second one but the thing holds like 5ml and if the second is the same as the first, thats a waste of 10ml. Any help would be appreciated. Thanks
