Be sure to read the directions on their site about first use. They also have a video to demo it for you. I don't know about the Evic but it should work fine on your Vamo.
I had one of those but will probably never buy another. Yes the flavor is great and good vapor as well. My complaint is that the quality control must be lacking. Seems that they last anywhere from 2 to 10 months. Realize that it will vary according to usage but I was quite gentle with mine and only got about 2.5 months. I realize that only comes out to about 28 cents per day but with my
rba I can get that down to around 5 cents per day.
