What will you mostly use it for?
The AK820 Max is the more natural fit for buyers who want a ready-to-use keyboard, Hall Effect switches, or a smaller footprint. The GMK87 takes the edge for users who want a TKL kit and more explicitly described build materials for customization. Travel leans toward the AK820 Max based on its listed weight, dimensions, and larger battery. The 75% versus TKL layout is the main day-to-day distinction.
Pick the Ajazz AK820 Max
- The AK820 Max is explicitly listed with Hall Effect magnetic linear switches.
- Its 75% layout includes a knob and keeps the keyboard more compact than the GMK87's 80% TKL layout.
