I'm a little late to the party on this one but recently picked up an OBS Engine.
Pair of Staple Staggered Fused Clapton 0.3Ω 3.5mm ID at 0.18Ω installed.
This tank is something a bit different.
There are hundreds of tanks out, what makes this one special or different?
It doesn't leak!
While still being a Velocity style desk with holes in the base for juice feed but that is about the only thing that makes it similar to the others.
Wicking is definitely easy and only needs to reach the deck.
However you'll notice I went further than required and tucked into the holes in the base of the deck simply because I could.
This isn't required though.

The air runs across the top of the coil on this RTA instead of from the bottom.
Just below the drip tip there are three air holes.
7.7mm x 2.6mm
They feed the inner chamber leading directly to the top of the coil.
There is no other air, thus no place for leaking.
Not having an air chamber under the deck allows the tank to be a bit shorter.
Coming in at only 50mm tall from base to top of included drip tip and 25mm wide, this turns out to be a pretty impressive RTA.
Drip tip ID is 9mm tapering down to 5.65mm.
It may look like a small tank but you can still fit 5.2ml of juice in.
A sleeve covers the 10.5mm x 4.75mm side fill on the top portion of the tank.
Nothing has to be removed or disassembled to fill with juice.
It produces a full bodied flavor and plenty of cloud due to the inner air chamber pulling straight off the top of the coils.
I was rather surprised at the amount of flavor from this little thing.
No flooding like some of the others that only have top air flow.
This means there is no juice sitting in the line boiling with each draw you take.
While I intended on writing up an entire full review, I found this one to cover it all.
Myself I did not encounter ANY of the negative spots this reviewer did, however they do cover all of the other info I did not.
