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
