Okay, I think I'm finally ready to do this thing..
I've had my 3.7v box mod for a week and it's been used enough for me to throw out an honest opinion. I LOVE THIS LIL THING! I am a very heavy vaper, and one of the batteries lasts me most of an entire day. I carry the spare just in case. The first time I took a puff on this device.. wow. I read a lot on ECF about warm vapor but to experience it was quite a treat.
as of a few days ago, I have retired all but one of my 510s (that I carry with me just in case..) and my PT has been in a case all week and the box has become my primary device. Even as much as I use the box mod, I'm not draining batteries as fast as I'm used to, and again I always have a fully charged spare that will hold me over until I get back to my charger. Because of this amazing mod, I am PIF'ing my 510 kit to a friend and family member so hopefully they will give up the analogs as well.
It sounds trivial, but I love that this thing is all plastic. My 510 batteries, and moreso the attys, are all niched up and scratched because of being in my pocket with keys, etc. Also, I don't carry my metal PCC because I don't want it to get scratched up. Yeah, I'm a bit OCD about keeping my things in perfect condition. Last weekend at a party my 510 slipped from my hand into the driveway and got some nasty scratches. The atty too, which was only a couple hours new at that point. Steve's mod on the other hand still looks great, even after being in the same pocket with my keys while I went out for a walk.
I love the size, it fits anywhere and stealth vaping is very possible (and handy!)
The one complaint I have about it is this: at my sons birthday party last weekend I got in a bit of trouble for taking a puff. I was told that I could "cause a panic" or something along those lines. I didn't realize until last night what that crazy lady might've been referring to.. this thing kinda looks like the remote bomb detonators you see in movies

either way, that lady can kma
I always show off my PVs and juice collection to everyone who will listen and, now, the only thing people are interested in (yeah, people who don't even vape at all) is this box mod. They keep trying to buy mine!
Well anyway I guess that's it. I just wanted to say thanks Steve for this amazing and affordable product and I can't wait to order my 5v! (or win a contest

)
