with SayoDevice O3C OSU Keyboard with Quick Trigger, Hall Switch, Magnetic Linear Switch, Button and Screen, Copy Paste, Shotcut, Macro Hotswap Mini

The refresh rate lives up and as a geometry dash player it’s perfect it helped me beat my new hardest sakupen circles I would definitely recommend for macros as well Overall an amazing product

it cannot be understated how good this little device is for geometry dash.I’ve used the Apex pro, the huntsman v3 black analog, the g502 and this thing performs massively better with significantly less input delay. If you want to perform at your best possible level, don’t spring for a £200 keyboard because this thing does just as much good for a fraction of the cost.

Excellent product, great software

Been using this since April of 2025, I've put my review at 4 stars because very early on i noticed that the knob had started to bug making it double click, its still useable to a certain extent with me having to use the button at a certain place to make it not double click, but overall everything works really well and ive also used my sayo device for gd for over 1.1 million key presses, this thing lasts along time and ill likely be buying it again due to it taking not much room because the size is very small. Next the buttons feel good quality and wont break easily. The 8K polling and the Rapid trigger is definately a game changer if you want to become a better player in gd/osu and you can definately feel the difference overall to a 1k keyboard. Lastly i recommend this product as you are able to change everything about the product screen, i have changed my menu on the drivers to showcase my own gifs/pictures meaning that it has great customisability.

Got it for kid for christmas , works great

i use it for gd its rapid trigger and delay time is very good i like it especially for the price

I bought this for geometry dash as one of my friends told me it was way better than using mouse. After using it for a few days to a week, I’ve improved so much. If you’re thinking about buying it for a similar reason, do it. It’s the best thing you could buy for this price.

Perfect, brought for my son who is addicted to geomatry dash and is on the extreme demon levels. He cannot believe what a difference this makes.. he struggled with the mouse but has got much further using this. Love the light up colour aswell.

osu!プレイヤーであれば絶対買うべきです。 通常のキーボードでも良いですが、手元配信する際にばえる為使用しています。 キャリブレーションも簡単で、更新自体もすぐに出来ますしマッピングも楽でした。

Excellent 👌

Muy buen dispositivo si quieres mejorar en GD No lo pienses más, compralo bro.☠️

Compré este teclado compacto con interruptores magnéticos Hall para usar en juegos y tareas rápidas, y la verdad es que me ha sorprendido. La sensación de las teclas es muy fluida y responde rápido, especialmente al jugar o hacer atajos. La pantalla y la perilla son detalles útiles que no esperaba y le dan un extra de personalización práctico, sobre todo para macros o accesos directos. El tamaño es ideal para tenerlo junto al teclado principal sin ocupar mucho espacio. La configuración inicial fue sencilla y no he tenido problemas de conexión desde entonces. En general cumple bien para su precio y me ha resultado una herramienta versátil para juegos y productividad
