I bought two from Ovale recently. Quick delivery, good one stop shop for most ego stuff in general. I've been using one for about a week too, and enjoying it. I'd say my only complaint is that it gets a little hot in the cone area, if you chain 5 or so vapes. It cools down quickly, but it'll affect the taste if you go at it right away. It's not as bad as it sounds, but that's all I have to say. Well, I should say that it's 3.7v. Unlike 3.4ish Egos. I wonder if these attys are more suited to actual Ego voltage? It's a minor difference, but maybe just enough that I think these deserve their own attys. Maybe.
