Clearomizers with cinnamon juice.

[Beaverkt]

my girlfriend loves cinnamon juices. Right now she is using a small vivi nova with one of the metal tanks. She is interested in other devices. Specifically other clearo type devices. She has a tendency to not refill often enough and thus burn carto tanks. So my question is what other clearomizers are safe to use with cinnamon juices ? I believe that the new kanger protank should work but she would prefer something ego sized.
