Keyboard and Mouse Bundle Cougar DEATHFIRE EX — hybrid full-size USB keyboard, QWERTY, 8-color RGB backlight; mouse ADNS-5050 2000 dpi, black

The Cougar DEATHFIRE EX bundle contains a full-size wired USB keyboard with a QWERTY layout and an eight-colour RGB backlight, paired with a black gaming mouse that uses an ADNS-5050 optical sensor and supports up to 2000 DPI. Both devices have 1.6 m cables and are designed for desktop setups requiring reliable wired connectivity.

Advantages

The bundle provides a consistent wired solution with ready-to-use USB connectivity and a unified black design. The keyboard’s hybrid mechanical switches combine tactile feedback with extended durability and support 19-key rollover to reduce missed inputs during fast sequences. Both keyboard and mouse offer eight-colour backlighting with multiple effects for basic visual customization. The mouse features Omron switches, responsive ADNS-5050 tracking and a 1000 Hz polling rate for low-latency input.

Suitable for

• PC gamers who prefer a wired keyboard and mouse combo
• Users wanting a full-size QWERTY keyboard with a hybrid mechanical feel
• Players seeking basic RGB lighting and several backlight effects
• General desktop users requiring reliable, low-latency input

When it may not be suitable

This wired bundle is not suitable for users who need wireless or Bluetooth peripherals. The keyboard uses a QWERTY layout and therefore may not match regional layouts such as QWERTZ or AZERTY without remapping or replacement. Additionally, the mouse’s maximum native resolution of 2000 DPI may be insufficient for users who require very high DPI settings.
