Hi,
just wanted to share my experience, I vape normally switching between Vivi Nova and Kanger T3, I like the fact that the Vivi Nova works fine with lower voltages and I don't need to have a mod on it, well I had a bad experience recently I have been using the coil head for around 3 weeks or little less, the performance of the coil heads of course decreases over the time but not in the way that you notice it right away, you need to open a new coil to see the difference.... well I started coughing 4 days ago everytime that I vaped on the nova without any reason, the flavor didn't taste burnt and nothing seemed wrong with the wicks.... I switched to the T3 and no coughing what so ever.... so I tried to clean the vivi and give it some rest to dry it out, when I picked up again, I started to cough again... I decided to open a new coil and voila.. cough is gone.
What I think is that is dangerous because there is no sign that the coil is worned out or burnt but you start vaping some strange material that makes you cough... and you may think that this can be an seasonal allergy or whatever... there may be something wrong with the silica wicks of the vivi novas.
