From what I've read, the eRoll is the best choice right now regarding cig-a-likes, but with so many different models around, you're never sure...
It definitely is.
I tried a Blu once but it sucks in comparison. The eRoll is basically an eGo-C in cigarette form factor and to me it's quite simply the "cigarette 2.0".
Not only does it taste better and most likely won't kill you. It's more practical in every regard and dirt cheap to boot considering that it has basically
no maintenance cost aside from the liquid if you treat the atomizers well or
get one of these.
Seriously this thing is one of the best gadgets I've ever bought in my life. I
always have it on me.
I have the black one. Paint doesn't come off easily at all. Mine have a few scratches but that's because I'm an idiot and keep dropping them on the floor all the time.
Whether you'll need both of them on travel really boils down to how much you're vaping.
If you handle this thing like you would handle a pack of analogs i.e. smoke like two cigs an hour on average, then one will suffice.
In the first few days, however, you'll definitely need both and lots of extra tanks or a juice bottle for refill because you'll be vaping on this thing all day
Edit:
Oh and I ordered mine
here.
They're a little on the expensive side but I ordered there like 7 or 8 times and they shipped within 3 days every time. Very reliable and most of their juices taste awesome. Spearmint and American Red in particular are amazing.
