If it’s the SXK BB, I’ve got the same one, and from what I understand it has one MAJOR difference from the authentic Billet Box...it has a micro USB port, which will allow the use of the eScribe software without having to make modifications to the mod! Pretty sweet little mod. I recently got a cloned version of the Boxer RDTA, it’ll allow some decently larger builds in it. Between it, vape shell, Exocet, the Kanger RBA deck, and both of the other bridges included with the SXK version, I can get anything from a great MTL to a pretty good (albeit fairly restricted) DL experience. Now I’ve got my eyes on that new SXK Bantam box, uses the same Boro tank so all BB paraphernalia will work with it, but half the size because it uses 18350’s.
