Also wanted to add that arizer the company is great right along with their product. I sent them an email with my concerns about buying my buddies "new" old model solo. Within 36 hours I received an email alleviating my concerns.
They informed me that if the ceramic bowl does happen to chip it's purely cosmetic and in no way unhealthy. And that they will have no problem covering the unit under warranty as long as I provide the receipt! Now I am more then happy with my m103, just ordered a few goodies.
Also just ordered a ryot 10inch axe bag. Seems like it should be able to store the solo, meds, small abv jar, grinder with its special tray thing. And the back up piece, ill update when it arrives
