Afternoon Fellow vapers, This morning I received the SXK Billet Box from @Sir Vape . I decided to go with the SXK clone because after a few attempts of trying to catch an Authentic, setting aside Saturday afternoons which are meant to be relaxing & doing more productive things such as work around the home, socializing, family time & catching the odd beauty in my life - just living life, rather than stress myself out over maybe laying my hands on a piece of metal, plastic & what not. The SXK Billet Box: Quality - excellent, solid & sturdy, anodized aluminium alloy. Side panels solid and fit snuggly - no rattling. Package contents - 1x SXK Billet Box, Set of spare O-Rings, screws, Aspire Nautilus coil adapter, Kanger Coil adapter & Kanger RBA adapter & RBA. Chip - Fitted with the Asmodus 70W chip - The same chip used in the Asmodus Ohmsmium & Asmodus Ares. Watts - 1-70W Temp Control supports Ni, SS, & Ti. Mech mode supported as well. Powered by a single 18650 battery - not included. I haven't spent much detail time with it the SXK BB as yet but over the next few days I'll keep adding my experiences. I built it using the supplied RBA & the flavour so far is excellent. Battery life outstanding, 3 tanks (15-18ml) and the battery is 1/3 remaining. So far I'm seriously impressed by this little device but time will reveal all. Well worth the money & then some & in my humble opinion a worthy alternative to the Authentic if one cannot afford the Authentic or neither have the time & patience as I.
