So here's my take on the Ghost. Beautiful vape. Hefty. The coolest and smoothest vapor that I have ever experienced but it comes at a cost............flavor and possibly potency. There are only two ways to cool vapor. One is through ice and the other is by increasing the length of the vapor path. Ghost has done this by using those multiple vape path channels (it'd be interesting to know if those channels were stretched out in one line, how long that would actually be) but by doing this, you are increasing the surface area for condensation to take place, ergo, loss of flavor and possibly potency. In the flavor department, it can't hold a candle to the MiniVap but......................the vapor is cooler, it's a LOT easier to set up and it gets up to temp really fast, while also being harder to keep clean. With all that being said though, if I needed a portable to use when I'm out and about and if I could handle the size and the weight, I'd be using the Ghost in a heartbeat. And in regards to the learning curve, all I gotta say is, what learning curve? Provided good vapor on the very first hit. Yeah, the first hit is a bit whispy but so is the first hit on the Mini but after that, things improve quite a bit. Really like it. Now if it had the taste of the Mini, it would be a home run but I can't see how, in a portable, one could get vapor that is that cool without losing some taste in the process.
