Si llega a presentar problemas, pantalla fantasma, actualizaré está reseña. As my ear pads were disintegrating I was afraid I would have to replace the headset. If it says amazon on it, must be quality. I CONSTANTLY get compliments on these and they look better after a few uses. I personally have pretty narrow feet, with VERY high arches that collapse inward when I stand up, so it sucks that they dont offer any arch support, but very few types of sandals do. The brake mechanism is made from cast aluminum, overall they just feel solid and good quality. Additionally, on the issue of whether you want linear or tactile switches, that will be entirely up to your personal preference. These slippers are just as soft and fluffy as the picture shows, but they run small. It?s comfortable and makes me want to wear it all day. old.
