Choose A if…
Logitech Signature K855
A compact wireless tenkeyless mechanical keyboard for productivity users wanting multi-device Bluetooth or Logi Bolt without backlighting or gaming-specific features.
Choose B if…
Logitech MX Mechanical
A full-size low-profile wireless mechanical productivity keyboard with multi-device switching, smart backlighting and Bluetooth/Logi Bolt connectivity.
These products already overlap on wireless; the deciding difference is more likely to be their distinctive use-case signals, exact specifications, current price and retailer availability.
Australian Product Guide does not currently have comparable maintained reference prices for every option in this shortlist, so price should be verified at the retailer rather than inferred.
None of the maintained options satisfies your non-negotiable deal-breakers, exact Australian model identity is unclear, or the evidence is too shallow for the decision you are making.
Exact model/variant, current retailer availability, current price, warranty/support terms and any specification that materially affects your use case.
