After using my Solo for 3 weeks now, I'm very satisfied with it! I had only a Vapir No2 to compare with and the Solo definitely takes it to another level. The Solo gives you thick and clean vapor. Battery-life is enough for my needs (unless I share a lot). It's very easy to keep clean, because the only thing which gets dirty are the stems. I also had no issues with loose or to tight stems. To me, they both fit perfect (alltough one takes a bit more pressure to put into the device than the other), the airflow is just the way I like it.
@glaze83: thx for the pics btw, very interesting! I'm not very familiar with the "inside" of electronic devices. So maybe you or anybody else can help with my issue (I'm sure, i'm not the only one... ):
Is there a way to shut down the sound when turning the unit on or when it shuts down? This is pretty annoying and sometimes suspicious, especially at the movies...
The other way would be, to disable the automatic-shut-down after 12 minutes.
But after all, the Solo is a great vape and my daily companion...
