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.

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

Use all the time. Great item

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.

Bought for gd, makes a world of a difference on 0.150mm RT

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.

Fell off with GD a few years back, but this has enabled me to play harder levels again. Would highly recommend it if you want to be more consistent! Setup is simple enough, though the actual config was a bit trial and error for me. Also, expect to get used to the device for a few days, it feels awkward for a little bit. Got it thinking that it wouldn’t make a difference to my Geometry Dash gameplay experience, but I’ve bounced back harder at the game than I have before. Beat 4 insane demons rather quickly, and I’ve progressed to 71% on Bloodbath in a matter of days.

Great gadget. Well made. Works well.

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

أبنائي يستخدمونه في لعبة جيوماتري داش ، ممتازة.

Knoppen afzonderlijk programmeerbaar. Dit device is van hoge kwaliteit! Wordt geleverd met USB naar usb-c kabel. Gebruik je uitsluitend usb-c, koop er dan een usb-c kabel bij. Klikt snel en foutloos!

This thing is amazing. So, so durable. Extremely accurate and provides an extremely high click per second capability. It comes with interchangeable keys, white and black and a cute little colored screen you can customize. One of our sons plays a fast paced rhythm game called Geometry Dash and this sayo device is highly recommended by other gamers. I say that it is durable because it has survived many rage incidents. This kid has destroyed mice, keyboards and even a nice 240 Hz monitor but this Sayo device has weathered all those incidents for nearly 18 months and still works like new. It's a little pricey, but so worth it knowing the quality and durability.
