O3C Rapid Trigger Keyboard With Hall Magnetic Switch For OSU Geometry Dash

I used this for geometry dash and its very nice! The customisable features are beyond limits, its fast triggering and overall amazing. The connectivity is easy to do, just plug it in and head to the website! I recommend this to people who want to get better at geometry dash because this says actually improved my skill! 10/10! Although, the price could be better.

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.

Good quality item great for geometry dash or osu good colour fits my setup perfectly small enough to not get in the way good price, won't break easily and it's really easy to use rapid tap/trigger really useful

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.

Great gadget. Well made. Works well.

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

For such a small device it has a lot of functionality in terms of the rapid-trigger function. It's easy to setup and can be done right on the device but the Web application will provide more adjustments For such a small device that provides rapid-trigger function it's a better value for money than the Wooting Uwu. It won't make you better at games though. Great device

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

tres bon clavier pour osu

Works perfectly

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

Qualität und Preis passen super gut 👍
