Compare Yunzii B87 vs IF99 Differences Side by Side

This comparison helps buyers decide between the Yunzii B87 and the Yunzii IF99. Both are wireless mechanical keyboards with gasket mount structures, but they target different workspaces. The decision is difficult because both offer QMK and VIA support, hot-swappable switches, and strong build quality at similar price points. The B87 is the more compact, potentially more portable option with an integrated wrist rest, while the IF99 brings a full numpad and a novel LCD screen. The choice ultimately comes down to whether you need the extra keys and screen or prefer a smaller footprint.
