Good vape, folks. I got this today, wrapped up a 2.5mm dualcore Clapton (Ni80, 28x2 inside, 38 wrap) and, after a little fuss, got this thing cooking at .64 at 26 watts (4.13V). I've just refilled, making this only 3 tanks worth of experience, but I will give my thoughts based on that...

It looks great. Solid, heavy and shiny, with deep, well-done engravings on both sides. This is as close to original as possible, but SXK is usually the best in the business at 1 to 1 reproductions. In the package are the rba, along with extra o-rings, gaskets, post screws, and 4 air inserts, which screw in under the coil. They range from 1mm to 3mm in .5mm increments. The 2mm was pre installed, but was promptly replaced with the largest, 3mm insert. This must be done before coil placement, but I have no issue there. A 510 adapter allows dry burning after set up.

The entire unit breaks down for cleaning, but basically it's two pieces, the tank and the deck. The tank is nice polycarb, thick enough to resist some damage. The chimney easily pops out, and the neck terminates at a swivel, allowing you to perfectly line up the bridge with the Billet's offset threaded nut hole- a nice touch, indeed. There is a rubber bung on the front, that fits normal bottles for filling.

The base is typical Reaper RTA all day- just two posts with flat head screws. This is the biggest drawback, as the screws don't trap well unless single wire or super fine claptons...a real disappointment, but not a deal breaker. imagine a Dvarw build and you're close. 2.5mm is the max coil I.D. I'd bother with, 3mm was shorting too easily for me. Wicking seems to be braindead easy, with two generous channels that encourage flattening and fanning out the wicks to dam the juice as it's gravity fed down to each corner. I was alarmed early on with the ease that the tank came off the deck, fearing it would get worse and leak when juiced up, but not at all....so far I've not experienced even one drop of leaky liquid, which I consider unusual to be honest.

One note is this Boro is meant to be filled upside down, and any other method will flood your deck and chimney. Actually it works quite well and is very neat and dry. The flavor, with my standard "boro" juice (strawberry coconut macaroon) tastes exactly like it's supposed to, and very punchy, like the VapeSnail or Bridg'D...it's obvious to me that the rectangular/oblong bridges really benefit from that extra room in the deck. Even my favorite, the Exocet 2, took this design, while rounding the corners. With the largest airflow of 3mm, I get a restrictive lung hit with little noise and little turbulence, though I wouldn't say "smooth". It's looking to be a very convenient and clean operating bridge...it even has multiple airflow entry points, to allow for use in the Delro, where the air comes In The back...

Well thought out, and nicely machined. Good job to SXK for bringing it to us for less than $150.00. try it yourself!
