Hey everyone, I'm new to the forums, but I'm an experienced vapor user. I just got the Itaste SVD a few weeks ago and it's been working great until recently. I am using a Samsung ICR 18650 2600 battery, and an Iclear 30 tank. Sometimes I push the button and it does an amazing draw. Other times I push it and nothing happens. Other times I push it and it turns green and then halfway through a draw, it remains green, but misfires (no vaping noise) and also other times I"ll hold the button and it turns green and misfires and I keep holding it and it just shuts off and I have to turn it back on. Now I have no idea if all of these issues are related to one problem, but I can't seem to figure out what is going on. Has this happened to anyone else?
