Review: Esta es una cámara de acción muy barata respecto a sus competidores de más prestigio, las Osmo y Gopro, evidentemente, no va a competir con ellas en muchos aspectos de calidad. Sin embargo, si cumple para lo principal, que es grabar secuencias de video, en mi caso, mis viajes en motocicleta. La cámara trae todos los accesorios necesarios para realizar esa tarea, soportes, bases, fundas batería, hasta tarjeta SD. Lo que yo si le reclamo es que siempre se esté desconfigurando la fecha y la hora, es mi mayor lío con la cámara, de lo demás, cumple y por su precio es una genial opción.
Review: Ótimo produto
