The Cthulhu is a great 1-1 clone of the original, there were slight traces of machine oil but after a quick wash it was good to go. All threads are good with no grinding or squeeking, build deck is not the largest but is relatively easy to build on. I did find that the post grub screws cut the wire if tightened too much and the allen key is tiny and potentially easy to lose (must find a spare) Installed an 8 wrap 26awg 2.5mm ID dual coil build @ 0.5ohms wicked with Japanese cotton, filled it with Dragons blood (top fill works great) and it vapes like a dream @ 30-40watts, great flavour and vapour production. All in all a very good sub ohm big air flow atomizer at a very good price

Received in a clean condition with little or no machining residue, after a quick wash I built it with dual alien claptons @ 0.25 ohms, followed a wicking video on youtube and placed cotton halfway down the juice channels filled it up (after struggling to remove the top cap which had been over tightened during assembly) , stuck it on the Cuboid at 70 watts and this thing is both a cloud and flavour machine. No leaking or dry hits. Unless you make your own liquid, I would avoid as it is a real juice guzzler, but the vaping experience is well worth it.

Very clean straight from the box, gave it a quick wash and built using the supplied coils, easy to build and wick, filled it and it produces very good flavour and plenty of vapour. It is also supplied with the blanking parts for use with single coil builds and a spare top fill seal which are not shown in the product pictures.

Came well packaged in the standard plastic tube (end mill type), with a full set of spares and 3 additional airflow reducers 3,5-4,0-4,5mm (that are not shown in the pictures). The 3mm reducer is installed as standard. Gave it a quick wash and installed a 24awg, 30awg clapton (0.3ohms) (capturing the wire is tricky but doable) wicking is easy, filled it with my custard donut set the mod at 40 watts, and the flavour from the first draw was sublime and continued to get better. A great clone of a great tank.

Very good 1-1 subtank clone, no machine oil or swarf to be found. Performs as well as the original Subtank with no signs of leaking. Stock coil is not the best but is usable.
