We have used Focalecig successfully for all our 18650 battery purchases since November. I would almost be certain our green Panasonic 2900PFs and 3400Bs are genuine.
There is a Certificate of Authorization under the Panny/Sanyo products' information tab on the FC site.
I haven't noticed a COA anywhere before and and am not sure what weight it carries but we found it reassuring.

Kraken clone, X9 dct tank, wool and wire all arrived intact and spot on to tracking timetable, that $13 Kraken is lovely looking but the screws are a touch loose, done a hard and fast u wick and its sitting there gleaming after a good run over with the Duraglit wadding but letting it wick up a bit before going for a proper test vape.
X9 tank is also soaking up a bit, cost about six dollars and is a little gem to fill with the fill ports and very clean design so thats a plus too
What I liked about Focal too is that the Origin brass I ordered they managed to get it to the carriers before the holidays set in and its on its way through customs, so they got my business for the foreseeable and I have asked Paypal to retrieve my money from VaporBreak who I was really pleased with but just ignored my emails and attempts to speak with them
Ok so here are some pictures of the Marstech QQ cartotank mech mod, and a T3 clearomizer ... I haven't used it yet, but I took it all apart, the initial impressions are very good. It feels solid, all the threads work well, no ill fitting parts, and two nice surprises which were a floating 510 center pin on the carto tank, and a removable drip tip which means you can use other 510 drip tips (2 out of 3 that I tried worked well, good fit) ... oh, and I remember someone asking if the fire button had a lock, and the answer is yes it does.
I also liked that the cartomizer is double punched, and you can dissemble the entire tank ie: top and bottom cap, tank, and carto for cleaning ... the telescopic tube squiks a little when adjusting, but moves in and out with ease, no sticking.
The T3 clearomizer is well made, equal in quality to the Kanger Evod and the like ... from what I can see, the coil head is positioned nicely inside of the clearo, so hopefully this will make for good wicking, and a vape similar to the Evod, but I still have to fill and use. All in all it looks really good, and I am not disappointed based on initial impressions, and I shall return will an update/review after I actually use it.
and Kanger Protank II for 9.99 (you will probably have to cut and paste this link as well) And I believe that you have to "buy" from this page in order to get the Group Buy price?? I think 
... its so cute, and it brings back found memories of the old days 
I hope this answers your questions. 
Ok luv ... here are the pics I promised. In the pic with the three coil heads, left is the Marstech T3 coil, middle is a rebuilt authentic Kanger coil, and far right is a knock off Kanger coil. You can see that aside from my longer wicks, the left and middle coils are identical to a T. You can also see that I installed the Kanger coil into the base, and the clearo itself and it fits just fine, even with my super long wicks.
