Well, I just did my first build on it. I did my standard mech build, a 6-wrap dual 24g, 2.5mm i.d.. I won't get too into it since I haven't put it through its paces yet. I'm sure my opinions on it will change as I get better acquainted with it.
The first thing I noticed about it is the o-rings. If you thought the troll was snug, you were wrong. I don't know what it is with wotofo and crazy tight tolerances, but it's a thing. The o-ring on the 510 drip tip adapter is so tight that I couldn't get it in all the way at first.
On the flipside, I don't think leakage will be a problem, both because of how snugly the barrel sits on the deck and how deep the juice well is.
The deck itself is very nice and easy to build on. The grub screws make it much easier to get a good, solid connection. The post holes themselves have a slight bevel to them, which I'm thinking will help with thinner wire. I haven't tested that yet.
Now, let's talk about the airflow. It's actually a fairly tight draw, definitely a bit tighter than the mutation x v3. Don't misunderstand me, it has a lot of airflow. It just doesn't feel like a lot of airflow. I wouldn't call that a con.
Flavor-wise, it seems to be lacking just a little, though the cyclone airflow does seem to add a lot to the vapor production while also reducing throat hit. I mean, this thing really chucks and it just feels effortless. The temperature is also much lower than one would expect for the draw. This might actually be the smoothest vape I've ever had. The chuff loosens things up a bit, but I find I'm liking it more with the back-pressure from the tighter 510. I think with the right build, the flavor on this atty will sing.
If you like to have a mellower and somewhat restricted-feeling vape that's still dense and cloudy, then this isn't a bad choice at all. I wouldn't say it's a super-noteworthy atty - it's certainly not one of those must-haves, but for the price, I'm not complaining. It's definitely something different from what has become the norm in ways that I'm finding hard to describe. It's a great atty. Glad I bought it.
