I use the AltSmoke eGo Passthrough with 510 Nano Clearomizers. Contained within is a review of these components. Use the following link to check it out yourself: http://altsmoke.com/#a_aid=515d9bdb95f28

1. So I started smoking e-cigarettes in summer 2012. Initially, I bought a
$59.99 starter kit from Green Smoke, which is typical. When you first start
smoking electronic cigarettes, the terminology — cartridges, cartomizers,
clearomizers, e-liquid, etc. — can be awfully confusing, so most people start
with a convenient starter kit!
Anyway. So a few months into smoking Green Smoke, I noticed I was
spending about $150 a month on my cartridges, which are basically e-
cigarette “packs” that contain pre-filled nicotine juice.
So then I decided to start filling my own cartridges, so I switched to V2
Cigs, a brand that sells both empty cartomizers and e-liquid.
Months later, I began to grow frustrated.
#1. My e-cig was malfunctioning every 3 months.
#2. A lot of e-liquid always leaked out of the cartomizers.
#3. I was still spending money out the ass.
So I then got back on Google and searched, searched and searched — and
read, and read, and read — until I stumbled on AltSmoke's Ego E-Cigarette:
So a couple things caught my eye about the Ego. First of all, it's USB
passthrough. So that means I can plug it into my computer and smoke it
without having to wait for the charge. And what's cool is that it charges even
when I'm smoking it. So long as it's connected to the PC, it's getting a
charge.

2. So when I decide to go out and grab some fresh air, I just detach it from the
USB cable and go smoke. Very cool.
Another thing is that it's compatible with 510 Nano Clearomizers, which
hold about 1mL of e-liquid juice and are both easy to use and refill. And the
e-liquid tastes good from it. Here is what the eGo looks like with the
clearomizer attached:
Yes, it's kind of big. Anyway. So I love the eGo and continue to use it. And I
haven't had to place it yet, and I'm already 6 months into this. The only thing
I hate, I suppose, is that I have to spend about $10 every 3 to 4 weeks on
replacement Clearomizers. The Nanos don't last as long as I'd like, but
they're the best 510 Clearomizers I've found thus far, so I'm sticking with
them.
In conclusion, AltSmoke is a GREAT brand. I trust them and I am glad as
hell I discovered them. Best of all, my total expenses (clearomizers and e-
liquid) have dropped to an average of $50 a month. :-).
I don't blame you if you chose a starter kit or are in fact considering a starter
kit (if you're a newbie), but if you've been doing this for awhile and are
ready to upgrade unto the upper echelons of e-cigarette life, then I highly,
highly recommend Altsmoke.
