Amazing product! Would recommend for geometry dash!Improved skill!
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.

Very cool little device!
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.

Small, light, and fun to use
I enjoy this device and use it for GD with no issues. One switch on mine has a light that does not work but the rest function well. Customisation is strong and the screen lets you add your own gifs and pictures. The memory is small so you need to limit how much you store. The switches feel good and respond fast. The size is light and compact which makes it easy to place on the desk. Good overall experience.

Best Geometry Dash Device for bad setups with poor latency.
Perfect for GD. It is very durable. It is very easy to use. The color of the screen is perfect! It has a USB-C Cable, and it works very well with computers! I do not recommend buying for mobile devices, as due to the Operating system, the device runs with severe delay.

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

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!
