Service is great. On my particular unit the screen was a bit buggy but seems to be working fine now. The keys need calibration often from what I've seen but still works amazingly well. Easy to use and to set up. You can customise the LED lights and the screen on the device which is very handy. The keys feel amazing and the utility of the buttons are great as well, as you are able to map them to any key on a regular keyboard on Windows, MacOS, and Linux. Absolutely amazing for the price. ### ⭐⭐⭐⭐⭐ Perfecto *by on Reviewed in Mexico 5 September 2025* llegó en perfectas condiciones, realmente lo utilizo para jugar osu y es bastante cómodo. ### ⭐⭐⭐⭐⭐ حجمه صغير ودايما ابني يستخدمه وسعيد *by on Reviewed in the United Arab Emirates 25 December 2025* اكثر شي ابني سعيد فيه ## Frequently Bought Together - BTXETUEL SayoDevice O3C++ OSU Keyboard Rapid Trigger Hall Switches Magnetic Linear Switches Keyboard with Knob and Screen,Copy Paste,Shotcut,Macro Hotswap Mini Keypad (Black) - One by Wacom Small Graphics Drawing Tablet 8.3 x 5.7 Inches, Portable Versatile for Students and Creators, Ergonomic 2048 Pressure Sensitive Pen Included, Compatible with Chromebook Mac and Windows - BTXETUEL SayoDevice OSU O3C Rapid Trigger Hall Switches Magnetic Linear Switches Keyboard with Knob and Screen,Copy Paste,Shotcut,Macro Hotswap Mini Keypad.… --- ## 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.com.br/products/563247800-sayodevice-o3c-osu-keyboard-rapid-trigger-hall-magnetic-linear-switches](https://www.desertcart.com.br/products/563247800-sayodevice-o3c-osu-keyboard-rapid-trigger-hall-magnetic-linear-switches) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-08-31*
