Had my Supreme now for 1 month. It hits like no other. My first high wattage device for me. Using a Stillare dripper tip. I use this one more in the evening because of its size and wight in my pocket. But lately if i'm holding it just right the bottom of my palm contacts the battery end cap and it heats up quick. I saw one other post by thatguyluqy (in the evic supreme thread) but he had to send it back. I have felt this one some other cheaper pens. They run a ground wire down the battery and I have had it touch the tube. But the Evic is different, with a removeable battery it doesnt have that. It not a huge deal, but it can catch me by surprise. I almost thought it was a shock at first, before I realized it was the heat. It may even be normal for that wattage. Chime in with some comments. I could use the posts. Newbie. LOL. If I get enough post, I can message thatguyluqy and see what the outcome was.
