I brought this device for one thing only, geometry dash. Works well on all platforms (mobile included).Would recommend for all others! ### ⭐⭐⭐⭐⭐ Review from an all time mouse player *by on Reviewed in the United Kingdom 9 February 2026* I'm mostly used to using a low hz mouse for geometry dash. Never touched the arrow keys or space in my months of playing. Switching to this, it feels much smoother and things feel easier. I now realise my mouse was NOT as fast and smooth as I thought it was...If you're unsure about getting used to playing with a sayodevice, it's been about three hours now and I'm already used to it. I'm working on acu right now and had about 40 percent learned and I'm up to about 80 now. It's much easier to control (when you get the hang of it, may take a bit to feel comfortable). Experiment with grips too!! If you're scared of wasting money on something that you may not be comfortable with, I'm WAY more comfy playing with this now. All up to preferences though!!Thx so much for this godsend of a device ### ⭐⭐⭐⭐⭐ Great piece of kit *by on Reviewed in the United Kingdom 23 April 2026* Well made sticks to most surfaces. Very responsive. Used for Geometry Dash. ## Frequently Bought Together - BTXETUEL SayoDevice OSU O3C Rapid Trigger Hall Switches Magnetic Linear Switches Keyboard with Knob and Screen,Copy Paste,Shotcut,Macro Hotswap Mini Keypad.… - 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 - HUION Artist Glove for Drawing Tablet (1 Unit of Free Size, Good for Right Hand or Left Hand) - Cura CR-01 --- ## 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/562734481-o3c-rapid-trigger-keyboard-with-hall-magnetic-switch-for-osu](https://www.desertcart.jp/products/562734481-o3c-rapid-trigger-keyboard-with-hall-magnetic-switch-for-osu) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-15*
