Mine is like that too. Very tight at first but now so loose that I worry taking it outside. Other people have said it's not really an issue and it gives you the bonus of better airflow, but I don't know, it seems REALLY loose. As much as I love the solo I'm not massively happy with the extremely loose chamber and much shorter battery life than expected.
Don't get me wrong, the solo, when you allow for these problems, is a really really great vape. It's what I use most of the time. But for the purposes of portability and convenience, the unsettlingly loose bowl and under an hour battery life is a let down.
Under an hour? huh? what temp speed are you using? 7?
About it being loose...there's nothing do about it- that's what happens to the materiel when it gets hot...its not an issue IMO but I mostly hold it upside down anyway.
