El calor que emite no es suficiente
Style: Usb
El calor que emite no es suficiente para enfrentar temperaturas de menos 38 F°. Salí en mi motocicleta y los probé y no sirvieron de nada. No lograron calentar mis manos. Obviamente usaba guantes y el nunca penetraron el material del guante. La temperatura era de 38 grados y llevaba protectores de puños para evitar el golpe del viento directamente.
