this is making me mad. I started out with 3. The first one died within 5 days, completely burnt out. The other 1 hardly produced any vapor, and the final one has a constant burnt taste to it. I ordered 6 more from cignot.com. got em 2 days ago. Decided to bust out one last night and give it a go. blew all the primer out, took a few puffs/exhales, then threw on a cart and puffed til i got the nastyness away. It worked fine until about 7pm tonight. Now it has a nasty burnt taste like the others. Im using carts with the blue foam mod and a coffee stirrer. I've been extra careful to make sure i wasn't vaping it dry. topping it off whenever the taste even changed slightly. i can see the fiberglass stuff under the bridge and it doesn't look burnt at all. looks new. still tastes disgusting. I am trying another atomizer now. Hoping i have better luck. Any suggestions? i'm starting to get really frustrated with this.
