Compare Yunzii AL65 vs AL66 Differences Side by Side

This comparison is for buyers deciding between two nearly identical 65% aluminum keyboards from Yunzii. The decision is difficult because both share the same gasket mount design, PBT keycaps, and tri-mode wireless connectivity. However, the AL65 packs a significantly larger battery and supports full QMK/VIA reprogramming, while the AL66 adds a metal knob and a slightly different sound profile from its polycarbonate plate. Your choice will depend on whether you prioritize battery life and software customization or tactile hardware controls.
