“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.”
Jeff E.Verified buyer· via Epomaker
Critique
“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…”

“The only bad thing is that the software is pretty hard to found, I don’t even know if it’s out there actually, anyways the product fantastic, the switches are smooth and lubed and the quality of the product is excellent”
MarcosVerified buyer· via Epomaker
Critique
“Good switches, nice keycaps. Shitty outsated driver. Some rgb doesn’t change even when using its own setting, doesn’t work with signalRGB. Sometimes when I turn on my pc the keyboard glitches and i have to switch to and from wireless mode for it to work…”

FAQ

Ajazz AK820 Max vs AULA EA75 Max: your questions

The Ajazz AK820 Max features Hall Effect magnetic switches, which use a magnet and sensor instead of physical contacts. The Epomaker EA75 Max offers traditional mechanical switches, including silent linear options like the Cotton Candy switch designed to reduce typing noise.

The Epomaker EA75 Max has a larger 5000mAh battery, while the Ajazz AK820 Max has a 4000mAh battery. Based on specifications alone, the EA75 Max has the potential for longer use between charges, though actual battery life depends on usage patterns like RGB brightness and wireless mode.

Yes, both keyboards feature hot-swappable PCBs. The Ajazz listing confirms hot-swap capability, and the Epomaker specification states it supports 3-pin and 5-pin mechanical switches, allowing you to change switches without soldering.

Yes, both product listings include Mac support in their specifications. The Epomaker EA75 Max description explicitly states compatibility with Windows, Mac, and Android, though it notes Mac modifier keycaps are not included.

According to its vendor page, the EA75 Max includes the keyboard, a detachable USB cable, a 2.4GHz receiver stored on the keyboard, four extra switches, a 2-in-1 keycap and switch puller, and user manuals.

The Ajazz AK820 Max vendor description mentions a silicone layer at the base, flanked by two cotton layers and an IXPE switch pad to dampen keystroke noise.

The Epomaker EA75 Max technical specifications state it uses plate-mounted stabilizers and notes they are not compatible with screw-in stabilizers. This limits your stabilizer upgrade options to other plate-mounted varieties.

The Epomaker EA75 Max provides more detailed wireless performance specs, listing a 1000Hz polling rate and 1-8ms latency for its 2.4GHz mode. The Ajazz AK820 Max lists Hall Effect switches which are favored by some gamers, but one vendor review mentioned latency issues in wireless gaming, suggesting wired mode for best performance.

Yes, both product listing pages include download links for their respective drivers. The Epomaker EA75 Max description states its software allows for key remapping and macro recording, but customization requires a wired connection to a PC.

The Epomaker EA75 Max specifications list a typing angle of 5 or 6 degrees, aided by a 2-stage adjustable kickstand. The Ajazz AK820 Max vendor description mentions a double-stage adjustable footrest but does not specify the resulting angle.

The Epomaker EA75 Max features south-facing RGB lighting and double-shot PBT keycaps. While the listing confirms per-key RGB, it does not explicitly state that the keycap legends are shine-through for the backlighting.

The Ajazz AK820 Max is lighter at 850g compared to the Epomaker EA75 Max's 958.5g. Their footprints are very similar, but the lower weight gives the Ajazz a slight edge for portability.
