Love the sound, the RGB is insanely bright. GravaStar might just be my favourite brand now. Got this on sale for $149. If you like the design, you'll be happy you bought it. I love RGB, but with the transparent keycaps, I had to put the brightness on 1 Pros: Lighting - Man this thing is bright Sound - Thocky/clicky sound is great Keycaps - They feel great to use Case - I "LOVE" this design. It has some weight to it too Cons: Lighting - Too bright at max brightness with included keycaps The alien design is awesome, the RGB is crazy bright. I now have the Mercuty V75 Pro Neon Graffiti and it's just as crazy too Highly recommended ## Frequently Bought Together - GravaStar Mercury K1 Lite 75% Gaming Keyboard, Gasket Hot Swappable Mechanical Keyboard, Pre-lubed Linear Switches, RGB Backlit - Transparent Black - GravaStar Mercury M2 Wireless Gaming Mouse with 26,000 DPI, PAW3395DM Sensor -79g Lightweight Hollowed-Out Design -5 Programmable Buttons -5 Dynamic Lightsync RGB - GravaStar Keyboard Wrist Rest Pad - Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/666142877-gravastar-mercury-k1-lite-75-wireless-mechanical-gaming-keyboard](https://www.desertcart.jp/products/666142877-gravastar-mercury-k1-lite-75-wireless-mechanical-gaming-keyboard) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-07*
