La calidad está por arriba del precio. Crei que los materiales serían más baratos pero en realidad son de buena calidad, tiene muchas buenas características, la correas magnéticas se ven super y parecen seguras de usarse. En cuestión de diseño UI y la personalización le doy un 5/10 por qué no se pueden diseñar esferas, solo permite cambiar el fondo de pantalla pero no la fuente de la letra ni el diseño o tamaño de números o información en pantalla. Pero aún así comprare uno o dos más para regalar.
