Recently I found out why I was having such a hard time with atomizers, It didn't seem to matter what I did they would always degrade after about a week of use. I had an atty taken apart to see why this happens. I only use cinnamon based juices. Apparently the cinnamon type juices can cause plastic parts to break down. In most atomizers there is a small plastic cup at the bottom. The juice seems to cause the plastic to break down and gel, The concern here is that if you somehow vaped this you would be inhaling plastic. (i think most people would stop due to the burnt taste this would cause) I'm currently trying to find out if this particular juice uses cinnamon oil and if so possibly conducting a test to find out 100% if it is what is causing this. I'm not going to mention a vendor because there are tons of cinnamon juices out there and im 95% sure the cinnamon oil is the culprit. Has anyone else had this problem? I think people need to know because this could cause a dangerous situation with the atomizers. Cartomizers should be fine as they are poly fill.
