I have heard of it and wouldn't bother. If they're consistently $200 bucks, buy a Provari or other high end mod instead. Lol I started with the fantasia e hookah for 40 bucks and after researching, discovered it to be an ego battery with some type of ce4 clearo. The battery it came with is actually a good ego battery though, its lasted for something like 6 months and I just sold it and a kanger mini protank II to a buddy for 20 bucks. He hasn't bought a pack of cigarettes in 2 weeks!
