What will you mostly use it for?
The K6 Pro is the more suitable choice for remapping-focused work, ISO layouts, and buyers who prioritize a lighter board. The AL66 stands out for a wireless setup that includes 2.4 GHz and for its physical control knob. Modders get more explicitly documented firmware and switch customization options with the K6 Pro, while the AL66 offers a gasket mount and polycarbonate plate. Both can suit different gaming or creative setups, but the choice depends on whether the K6 Pro's listed polling rate or the AL66's extra connection mode and knob matters more.
Pick the Yunzii AL66
- The AL66 offers 2.4 GHz wireless alongside Bluetooth and wired connections.
- Its metal knob can control RGB modes, brightness, or volume.
- The K6 Pro lists a 1000 Hz polling rate, while no polling rate is specified for the AL66.
