FocusEcig the manufacturer of the SKYFALL RDA Squonk tank, kindly sent me this product free for testing & review. For those that don't know what Squonk is, it is a term used to describe the sound made when using a bottom fed RDA, which is usually done with a refillable juice bottle inside your mod. These mods are generally either hard to obtain, expensive or both, although more are becoming available made cheaply from China but good ones are hard to find. The Skyfall does things a little differently, it still feeds the RDA from the bottom & squonks but it is a self contained unit, separate to your mod. This means you can use it to squonk with on any mod of your choosing! This is IMO a very innovative product & a bit of a game changer, it opens up a different method of vaping to many more vapers! Unboxing: The Skyfall comes in one of those hard plastic cases which I quite like. On the back side of the case there is a lot of information written on the cardboard inside, these are the only instructions provided with the Skyfall & unfortunately they do not make it very clear about how to fill the tank (more about that later). Flipping to the front of the box, we can see the Skyfall itself & an included Stainless Steel chuff cap plus a bag of spares, housed in a foam insert. On the Side of the box the word Skyfall is proudly displayed. Opening the box up, & removing the foam insert reveals a sheet of organic cotton, in a plastic zip lock bag, however the box itself has a very strong odor of either glue used on the foam insert, thinners or some kind of solvent used in the cleaning of the device. This odor had permeated into the cotton, even through the bag, so I will not use the cotton provided & recommend that if you do, you check/smell it carefully before using it. Not a big con, I have plenty of good wicking material of my own, as most vapers who buy this device will but for some vapers, this may be their first Rebuildable device & if it is I recommend adding some organic cotton wick to your order. The bag of spares includes 2 screws for trapping wires, the screws used in the Skyfall for positive & negative terminals have large screw heads, your magic blue screwdriver is not going to work well on these, I found a size 1 or size 0 posidrive screwdriver (not phillips) works best with them. Also in the bas is a spare spring for the pump section in case you lose one, 2 premade coils, a spare insulator, a spare positive post nylon screw(this fits on the underside of the RDA), spare o-rings & a Standard (non-BF) 510 pin, to allow you to use the RDA as a stand alone without the tank. A nice selection of spares here, perhaps adding 2 spare springs would have been better but you won't be needing to check the springs or take them out very often, so 1 should be enough in case you have 1 fly off & lose it. Setting up: As already mentioned the Skyfall box had a strong odor inside it, thus cleaning this device before use is essential. For this I took the RDA & tank sections completely to pieces & in sniffing the inside of the tank detected the odor on these parts too. I even went as far as to break the pump section down into its component parts before washing everything in hot soapy water & allowing it to soak for a while, before rinsing & allowing to dry. Thankfully the odor wasn't present after a thorough washing. Pump disassembled: All parts broken down, cleaned, dried & ready to be reassembled: Bottom feeding comes through the BF 510 screw then out at either side of the screw, at the lowest point possible, which is below the bottom of the main juice well, this means excess juice is removed more efficiently than on some other BF RDA designs. The RDA uses a 2 post design, these are at opposite sides, leaving the center of the RDA post-less, the post holes are very large, as you can see the 2mm shaft on my magic blue screwdriver slide through with room to spare.
