What will you mostly use it for?
The AK820 Max is the more compact pick for gaming and travel, and its magnetic-switch design gives it a specific appeal for switch experimentation. The AK870 suits buyers who prefer a TKL layout or want its more fully described screen functions and south-facing RGB. For general office use, the listed connectivity, sound dampening, and TFT screens are similar enough to leave the choice open. Both boards omit a numpad.
Pick the Ajazz AK820 Max
- The AK820 Max uses Hall Effect magnetic linear switches, a feature the AK870 does not list.
- Its 75% layout measures 333 mm wide, compared with the AK870's 80% layout at 370 mm.

“This keyboard is designed to work with windoz and Mac. But I can't find Apple replacement keycaps anywhere. This is the only reason it gets 4 stars instead of 5.”
“Launching a game makes the board thinks it switch to Mac mode, swapping Alt and Win key. This is random and will usually happen when launching a game. The only fix I know is to unplug and replug the keyboard over and over again until it thinks its in Win mode…”

“I love this keyboard. The sound is slightly clicky and mostly creamy. Super smooth to work on. I’ve also set up the RGB to match my PC ones.”
