It would have made more sense if they had multiple chips with different functions. A VW chip, a TC chip, a VV chip, an unregulated chip. Each chip has its own single function, and not multiple functions. Have the mod include two of the chips, like VW and TC, then sell the other two separate and have a full kit option that comes with everything. It would make it more work, but they could hone and perfect each chip (over time if they needed to) and have one mod that could fit most anyone's vape style, and do it well. They could also offer new and upgraded chips over time if it was successful enough (which is still possible). It would have made this mod more unique and they would not have ran into the whole issue of a pointless chip swap ability.
