Blu to Egos. The ego was good,as I did not know of anything better. Then I read on here about the Vamo,so I had to have one,well that lasted 60 days. I knew it was petering out. I had thread issues,then when I would press the button it would not fire,then it would just go totally blank. When the Vamo worked,I loved the power and vape. I needed better. The PROVARI!! I have only had her a few days,but this is where I should have been,since day one. I think of all the money I wasted on the Blu kit,the countless Egos,the Vamo. I could own 3-4 Provaris. Vape,learn,then end up with a Provari.
