Came earlier than I thought it would but still too late for summer; still worth hanging onto for next summer though. Battery life is impressive, and the build quality is pretty good. I have been hopefully purchasing nearly every metamorphosis of this sort of headset for years. The surface were applying it to is smooth and real marble. If you are looking for anything super formal or fancy, this isnt it. I mean REALLY fast. creo que depende de cada persona y el gusto de cada chancla por ejemplo yo soy talla 7 y compre 13 porque me gusta que haya chancla adelante y atrás de mi pie (sobrando) porque a mi parecer se ve bien y a otras personas les gusta que esté justa la chancla pero a mi parecer parece que te queda chica en general a mi mamá le compre 7 y ella es 5 y yo digo que se ve bien pero ella dice que la siente grande . Ive had it playing for a couple of hrs so far and was only able to get it to up to approx. Im usually a size 8, narrow foot and 7 1/2 fit perfect. I saw these here on Amazon and thought it sounded great, but after using, there was still a faint odor of my deodorant 😩 and it just didn’t smell overall fresh.
