I picked this up on the cheap since I needed a replacement tank, and it does its job well.

Pros: Building on it is dirt simple, and haven't had any trouble so far.
Airflow adjustment on the bottom is straightforward and nice to have.
for $11 it's hard to really complain about it.

Cons: the fitting of the top section of the tank onto the metal base does not feel that secure.
The O-rings don't give any resistence when putting on the top cap making it feel almost loose. Not to say that it's going to drain out your juice, but it does create a minor leak point that you'll need to wipe up after a while as you vape dependent on your build.

Love these guys

I love this little guy. Don't listen to the naysayers, this RBA packs a flavorful punch, comparable to RBAs and bridges two to three times the price. There's no leaking, as far as I can tell, and the hits are smooth and velvety. And the price point doesn't hurt either. The only con that I can think of is sometimes my mod (a Cthulhu AIO) says the coil's shorting out randomly when I know it's not. But that could be my mod, not the vessel...Anyway, its an excellent introductory RBA to the boro-verse. (Also, the shipping was, like. SUPER fast. THANKS SFV!)

SFV shipped this thing fast. I mean, I had it in my hands before I even hit purchase! The Vessel Builds, wicks and vapes like a dream. If the base would stay in place outside of the device, that would make it 5 of 5. I mean, o-rings and gaskets have been around since the first vape device rolled off the assembly line….making sure everything fits seems job 1 prior to shipping out to the World, yeah? However, my first statement holds true: this thing is easy to build, wicks easily and I can vape my face off with enjoyment all day.

The vessel is ok not the best flavor but easy to be build on as for straight fire vaporium there service is always great
