Trade-offs

• Limited to 19 keys, so it may not replace a full keyboard’s numpad for users needing additional functions.
• Battery life and latency details are unknown, which may affect wireless reliability for some users.
• RGB lighting and knob controls add complexity that may be unnecessary for users seeking a simple numeric keypad.
