Okay, I was looking for the Asmart Poldiac clone, but found out that if you drop it the threads on top break off real easy, so I don't want that. I want a 1:1 Poldiac clone, and the next one I find myself looking at is the Davapes clone. I'm wondering if anyone has one and what do you think of it? Does it work right out of the box? Any issues with it? Did you have to do any work on it?
