I've held off replying to this thread because I didn't want my first post to a normal thread to be negative, but here goes.
1. Thumbs down (for now)
2. I haven't had any major leakage yet, but I can't get rid of the burning taste. After I soak it in hot water, the bad taste goes away for awhile, but it comes back. My Nano has a very tight draw, and it doesn't put out very much vapor. A lot of people aren't having these problems, so it seems like a quality control issue to me. If S.I. can get the manufacturer to fix this, the Nano could be a good little clearo. For now, I don't mind being a beta tester if it leads to good clearos.
3. CE3 - I'm waiting on a larger capacity bottom-coil clearo that vapes as well as the CE3, is easy to fill, and lasts a long time. Maybe the the T3 or the other exclusive 3ml clearo Imagine talked about will the one
The search goes on.
