About Cosmic Byte Astra RGB Mechanical Keyboard

The Cosmic Byte CB‑GK‑33 Astra offers the ideal ratio of performance, portability, and customisation. You can easily switch between Cherry MX, Gateron, Kailh, and Outemu switches on this 67-key compact mechanical keyboard without having to solder anything, allowing you to alter your typing or gaming experience at any time.

Use Bluetooth or ultra-responsive wired mode to connect; you can pair up to three devices and switch between them with ease. While the 1,000 Hz polling rate guarantees low latency whether wired or wireless, the sturdy 1,800 mAh battery allows you to type for days on a single charge.

With 16.8 million colours and dynamic effects that can be fully customised using software or onboard shortcuts, per-key RGB lighting will add a stunning touch to your setup. During intense sessions, do you want to quickly control the volume? You’re covered by the user-friendly volume roller. This keyboard, which is now under ₹4,000 instead of ₹9,999, offers professional features in a small package for a much lower price.
