SayoDevice O3C OSU Keyboard, Hall and Linear Magnetic Switch, Button, Screen, Copy Insert, Shotcut, Macro, Hotswap Mini Pink

Thanks to this device my son can now beat grief and it is definitely worth it. I bought this for my son thinking what is this, but he loves it and is helping him beat many levels

My 13 year old son asked for this to play Geometry Dash on his laptop. I was sceptical but it is a really cool device with a little screen that he can customise with his own images/photos, I think he can change the colour of the lights under the keys and it also came with both black and white keys so he could choose which ones he liked best. I don't know much about it but it looks really good and he is very happy with the functionality.

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.

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.

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

Very high quality. Price to performance ratio is very good.

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

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

Excellent 👌

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
