El desbloqueo con huella muchas veces no funciona a la primera, tienes que colocar como regístrate la huella. Definetly reccomend everyone going up 1 size from what you normally wear! SUMMARY - I am very happy with the purchase and the price was reasonable. Great addition, and it also works like a champ. Opens & closes fine & no problems whatsoever. I have washed it twice and the stretch is still good but some hairs from the dog are not coming off without using tweezers to pull them out. o buscar una manera más fácil de instalación, pero aparte de eso si lo recomiendo porque si protege y cumple sus funciones. Its a shame too, because I thought the MSR7s had a beautiful, detailed sound, and the 700 Mk2s were absolutely amazing for bass. I tried the earbuds out and immediately noticed a complete lack of bass response in the right earbud. Im giving them 4 stars, instead of 3, because most of my issues were packaging problems and specific to my foot shape.
