Mine just arrived, and I tell you what, I LIKE this. I got the all black, and if I use this for a few weeks and don't experience leaks, I will be getting a second one.
First off, hand feel is GREAT. Fits very comfortably and perfectly in my hand. With the 'rubberized' paint, it feels like it was made for my hand. It is also a bit heavier than I expected, but not in a bad way. It just feels substantial, not cheap.
The bottle seems nice. Mine is currently soaking, I've been dripping with my Recurve on it to vape it a bit. The Pulse 80w bottles won't fit, too tall. However, the Pulse OG bottles seem like a perfect fit, but you would need to trim the tube down a bit. That mentioned, the tubing on the bottle has a smaller ID than some other bottles I compared it to. So while the Pulse OG bottle itself works, it may require tubing with a slightly smaller ID to fit well. The included bottle fits kind of loose on the connection in the mod, I'm guessing that since it has a good length of tubing that slides on, this is what keeps it from leaking, not a tight fitting tubing. Interested to see how well this works. The included bottle slides on/off the mod very easily, even when dry. Hoping this doesn't leak, the ID of the tubing already looks smaller than some others. Since the 510 connection for the bottle is so long in the mod, it slides a good amount into the bottle.
Fires well, my index finger falls right on the button where it should, and ring finger sits right on the bottle.
My main complaint right now is with inserting/removing the battery. So far I've only had a 21700 in it, but it's a very tight fit. With the + going to the top (positive is the spring loaded terminal), it's hard to get the battery in without damaging the wrap. Not sure if I jut need more practice or what. You kind of need pressure on the top of the battery to depress the + terminal, but you don't seem to have enough clearance without sliding it in at the same time. I can see where it chewed at my wrap a bit. I may just leave this battery in it and charge it via the USB since it supports 2A charging. Unless I learn better how to do this with practice, it will chew up wraps over time.
I really like it though, should have my bottle cleaned and filled in the next hour. If I run it for a few weeks with no leaks, I will most likely get another one. No hurry for that though since I prefer regulated mods. This is my first unregulated mod that takes a 21700 though.
Will post back later tonight or tomorrow once I get a little time with it.
EDIT: This may be one of those bottles that finally forces me to try one of my squonk refill bottles, lol. Just made a huge mess trying to screw the lid on. A few more tries as needed, maybe I'm just fat fingering it. If I can't get around this, I will be pulling out and washing a refill bottle.
