Our Verdict

Razer BlackWidow

Logitech K845

The Razer BlackWidow is better than the Logitech K845, although it's mostly geared towards gaming. The Razer has full RGB lighting, lower latency, and outstanding customization software. On the other hand, the Logitech feels better built, and you may feel less tired typing on it because it has a lower profile.
