I have been using a CE4 clearomizer, no issues with them. I decided to get a CE5 rebuildable clearomizer. After filling with e-liquid and letting it sit for about 10 mins I took my first hit from it and it had a very chemical taste, with the taste of the e-liquid in the background very muted. I thought it might have been the flavour of the e-liquid so I tried the other one I got with a different flavour and had the same issue. The vendor that I got them from says on their web site that you will have to vape a few tanks before you get the best results. Anybody else have this issue?
