The Qbix is an RBA that was designed by Atmizoo for the Aspire Prestige BOXX, which is a collaboration between Aspire, Sunbox, and Atmizoo. The Qbix comes with the BOXX deluxe kit, or stand-alone. It is basically a larger, Boro sized, DotShell. It has a 4ml capacity, but the EU version is 2ml until you remove the insert.
This bridge is compatible not only with the Aspire Boxx but all Boro-style mods!
