Fortunately his latest book improves on both of these faults. However, the sound quality from these are still lacking to me. He tried them on and immediately felt the little tag on the inside, which Ill have to cut out. The items advertised are size 5 and tan in colour those received both times were size 4. the threading is coming out on the side of it. A lot. He tenido el soporte por poco más de un mes y todo funciona muy bien. Strong and locks on. Easy to install but be mindful of the length of the bolts sticking out from under the carrier. I always wear Teva mush but I couldn’t find them anymore so I tried these.
