Battery

Build quality in the top 5% of 96% boards under $100.

Rules this board out

North-facing LEDs. Cherry-profile keycaps can hit the switch housing.
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.
