Build quality in the bottom 45% of 96% boards under $100.
- 96% ANSI layout with 102 keys, including a numpad and eight function keys.
- Hot-swappable PCB supports 3- and 5-pin mechanical switches.
- Bluetooth, 2.4 GHz, and wired connectivity, with a 4000 mAh battery in the metadata.
- South-facing LEDs. Shine-through legends stay dark, and some sculpted keycaps can clip the LED.
- Compact full-size layout. The numpad is present, the gaps of a full-size board are not.
Pick the Luma40 if your priorities are an unusually small ortholinear layout, CNC aluminum, and the stated QMK/VIA support. Choose the TH99 if you need a numpad and function keys, want 3/5-pin switch options, or prefer a listed silent switch variant. Before buying, check the Luma40’s low-profile-only keycap restriction and the TH99’s south-facing LED caveat against your intended keycaps.

What will you mostly use it for?
The TH99 is the practical pick for gaming and office work where a wider key selection or silent switch option matters. The Luma40 takes programming, travel, modding, and compact visual setups, particularly for buyers who value QMK/VIA and a lightweight aluminum build. Both offer tri-mode connectivity and hot-swap capability, but the TH99 accepts 3/5-pin switches while Luma40 is restricted to low-profile switches and keycaps.
Pick the Epomaker TH99
- TH99 vendor specs list 2 ms latency over USB and 5 ms over 2.4 GHz; Luma40 lists 3 ms over USB and 5 ms over 2.4 GHz.
- TH99 has N-key rollover and 102 keys, while Luma40’s 40% layout omits a dedicated function row and arrow keys.
