I think one thing I have trouble with is the toe loop because sometimes the chacos adjust too tightly while Im walking in them. I wrote to 3M and, basically, it was my fault for using them on textured walls. What a shame! Got them for 36CADtax in. Justamente lo que esperaba ! No tiene misterio ninguno conectas un extremo del cable a la salida optica del TV y el otro extremo a la entra optica del home cinema o barra de sonida que tengas, comprueba que al introducirlo suela el tipico click y se ilumina el calbe y listo. The "rotating" clamp is slotted so that it does not rotate. I recommend this shoe I was concerned at first about the color, as my fixtures are oil rubbed bronze, but with the appliances being stainless steel it looks perfect! I was able to do pull-ups without any tipping or anything.
