Our Verdict
ASUS ROG Falchion RX Low Profile
Logitech G515 LIGHTSPEED TKL
The Logitech G515 LIGHTSPEED TKL and the ASUS ROG Falchion RX Low Profile are wireless, low-profile gaming keyboards. The Logitech has a slightly larger TKL form factor, higher-quality PBT keycaps, and somewhat better build quality overall. Comparatively, the ASUS has a slightly smaller compact (60%) design. It also offers slightly better overall raw performance, supports Bluetooth multi-device pairing, and comes with a dust cover that you can store as a backplate. Unfortunately, we experienced occasional key chatter on our unit. However, it's worth noting that we haven't encountered many other reports online of this issue, suggesting it may not be very widespread.
