Copper is all the rage when it comes to Mech mods these days. The conductivity surpasses that of brass and stainless steels mods of the same design, but the Signum by Kontrabida Kustoms is in a different class, as there is no counterpart to its copper goodness.
The Signum is a 22mm device, constructed of a solid copper tube with brass end caps. Housed in those brass end caps are a telescopic floating center pin, and a recessed firing button. In the box, it comes with a 18650 tube, 18500 tube, and 18350 tube, all the same with the same solid brushed copper construction, emblazoned with the word “Signum” engraved right down the center. Check out the inside of the buttons, and you’ll find copper contacts, a delrin insulated 510 connection, and a simple, spring driven button (changeable to magnets easily).
The only fallback to the Signum, in my opinion, is the lack of a locking ring. Sure – with a recessed button, there’s a smaller need to be able to lock the device, but it’s never a bad idea to have a fail safe.
After a little dance getting the battery contacts all adjusted properly, I fixed up the Signum with my TOBH Atty clone. Right off the bat, after only using stainless steel mods before, I immediately noticed that this mod was a heavy hitter. My coils were firing quicker, and it delivered more voltage to my coils than before. This was proven when I hooked up a voltage meter, and found the drop on this mod to be at about .2 under load, much better than any other mod I had.
I highly reccomend the Signum mod. It’s an authentic, and a little pricey, but you get what you pay for. High quality materials, superior craftsmanship, and a serialized edition.
I purchased my Signum from Rob down at The Vape Room, and they still have a few left in stock if you’d like to make one your own.
