I talked a friend into an Ego-C like mine, which I love. But she only takes a small puff.."pushing button about 2seconds. Waaay shorter than normal......if there is a normal. But her atty gunks up in a day or so and she doesn't like the taste then....says it taste real bad. Is it because of the little short button pushes and the atty doesn't get to burn a little more while vaping? It the only thing I can think of that might be the problem.......I don't want her to give up.....what might be the answer? Should she hold button for a. Few seconds before then putting in her mouth to draw?
