Our Verdict

Logitech G613 LIGHTSPEED

ROYAL KLUDGE RK61

The Logitech G613 LIGHTSPEED and the ROYAL KLUDGE RK61 are different types of wireless keyboards. The Logitech is a full-size keyboard, while the ROYAL KLUDGE is a compact 60% size keyboard. The Logitech is better for gaming because it has macro-programmable keys and lower latency, but it doesn't have backlighting like the ROYAL KLUDGE. On the other hand, the ROYAL KLUDGE is better for mobile use because it has multi-device pairing with up to three devices at once over Bluetooth, it's easier to carry around, and it has a cable to charge it in case it runs out of battery. The ROYAL KLUDGE is also available in a few different switch types, and it's hot-swappable, but the Logitech is only available in one type of tactile switch.
